Pepper spray and kansas wind, no go. I agree with the street smarts thing. My apartment is next to an alley and i live in a bad neighborhood. If i see 3-4 young black men walking in my alley i go around them and come in from the street side. Actually pretty much anyone i would avoid, but definately the 3-4 young black men i described.
And BTW, screw racism, try racial profiling, and since im not a cop i can just admit to it. 90% of interracial crime is black on white. If you see 4 black men and you think, hey im not gonna be a racist and avoid them, ur asking to be a victim.
