I can't get over the way you worded this. That's like saying Detroit has a black problem or L.A. has a Mexican problem or Montreal has a French problem.
You're from Thunder Bay. You don't even have that large of an aboriginal population. Yes, native people in Canada have higher statistical likelihood of drug, alcohol, crime, gang activity, but saying you have a native problem pisses me off.
Most cops are decent. There are dicks out there but generally speaking, if you show a bit of respect and act like a rational human being, there aren't going to be problems.
