A Maple Ridge mother is horrified that riot police fired rubber bullets at her 20-year-old daughter, causing injuries, then arrested her and locked her up for over a day after she participated in a peaceful demonstration at the G20 summit Sunday. Elizabeth Rosenau doesn't believe there was any justification for what happened to her daughter Natalie Gray, who weighs 120 pounds. "I haven't been able to sleep. I'm in such shock and disbelief," said Rosenau. "Having spent two days watching and re-watching the videos of the detention centre protest I can only say that my whole family's faith in the police is deeply shaken. I cannot believe this happened in Canada, a place that people come because we have freedom of speech, freedom of assembly, a decent law enforcement system and justice for all. To watch that footage made me deeply ashamed of the police state that my daughter had to witness and be part of." Rosenau said her daughter was "incredibly shaken" and was "weeping" on the phone when she called to say what had happened. "She told me she felt this had changed her forever. I feel like I've been changed forever too," she said. Gray, who is a former Laity View Elementary student and French immersion student at Maple Ridge Secondary School, was one of the people who showed up to protest at the detention centre where police were taking protestors on July 27. Gray e-mailed The TIMES to say she was hit in the sternum and elbow by rubber bullets fired by riot police (The photo on this page shows the wound Gray suffered after being hit by a rubber bullet). She said she fell to the ground and was then "shoved into the pavement" by police, arrested and then forced to spend 30 hours in the detention centre. Gray recorded an audio statement after her arrest, which she sent to The TIMES. In it she said the protest at the detention centre was "entirely peaceful." "We were chanting and singing and clapping our hands," said Gray. Things deteriorated after a couple of unmarked vans drove up and "police or military" ran into the crowd and grabbed a couple of people. After that the riot police started moving forward towards the protestors. Gray was close to the front of the crowd and she became worried the riot police would use tear gas and grabbed a gas mask out of her bag because she suffers from asthma. However, she said she was complying with police orders and moving backwards. She then got shot twice with what she believes were rubber bullets. After the second bullet she attempted to get up but got shoved back down and police restrained her with zip ties around her hands. "I was absolutely terrified," she said in the audio statement, adding she lost control of her bladder. "I was in a lot of pain," she said. "Generally the officers didn't seem to care or take note of how injured I was." Gray said she wasn't told why she was being arrested at first but was eventually charged with obstructing a police officer. "I wasn't really sure what my charge could be because I was compliant with their orders when they shot me," she said. She was eventually taken to the hospital for medical attention and then to the detention centre where she was interrogated by three men and then strip-searched by four female officers. Gray said she was in "severe, massive pain" because she didn't receive painkillers often enough. She said after the strip search she was made to put back on her urine-soaked pants because there weren't enough clothes for all the people that had been detained. Gray said the toilets in the makeshift cells could be fully viewed by police officers. Eventually she was able to see a lawyer and was released on bail after a relative came to Toronto and put up a $1,000 surety. Gray described her time at the detention centre as "incredibly dehumanizing." Gray is currently under house arrest in Toronto at a friend's house until her August court appearance. Meanwhile, in Maple Ridge her mother can't believe what happened. She described her daughter as an "outspoken, strong-willed, passionate girl" but she said she's never been arrested before and has never been violent. She said her daughter became a committed activist after a trip to the Alberta oilsands while working for Greenpeace. She described how her daughter has decided not to get a driver's licence because she wants to only use public transit or walk or cycle to be environmentally friendly. Rosenau said her daughter is becoming a talented poet as well. Rosenau said she participated in protests in the late 1970s as a university student and "the police stood by and we protested peacefully." Rosenau pointed out her daughter and the other protestors weren't protesting at the G20 site. "They were protesting at the detention centre because they felt their friends were having their rights violated and were in there illegally," said Rosenau. "The leaders of the G20 summit were not under threat." The TIMES attempted to get comment from the integrated security unit for the G20 summit but a call wasn't returned by press time. More than 900 people were arrested last weekend during the G20 summit. On Tuesday the Toronto Police Service Chief Bill Blair announced there would be a review of "all aspects" of the G20 summit's policing. Both Amnesty International and the Canadian Civil Liberties Association have called on the federal government to conduct an independent review of security tactics during the G20 summit. The Canadian Civil Liberties Association released a report this week based on first-hand observations of over 50 human rights monitors. "It is the opinion of the Canadian Civil Liberties Association that police conduct during the G20 Summit was, at times, disproportionate, arbitrary and excessive," said an association media release. "In our view, despite instances of commendable and professional conduct, the policing and security efforts, especially after 5PM on June 26 and June 27, failed to demonstrate commitment to Canada's constitutional values. There's also a Facebook group calling for a public inquiry into the G20.
