EDMONTON/630CHED - As allegations of possible racial bias swirl around the paddy wagon investigation, the Edmonton Police Service is defending its record. A first nations member of the Mayor's advisory committee on multiculturalism says the incident involving homeless first nations people shows "there are very serious issues of racism in this city". Staff Sergeant Greg Alcorn tells CHED News racist behaviour is not tolerated from the top to the bottom of the EPS. Alcorn says from Chief Mike Boyd down police officers won't tolerate racist behaviour from anyone they deal with or anyone they work with. He says when hiring new police officers, EPS recruiters select from the best candidates available but also look for a cross section of society.
