There are no statistics (reliable) that back up your claim of a rise in incidents % per population.
Is there a heavy militarized police force here? Yes
Is it seen? rarely ever (this is not Ireland of the 80's or Israel everyday with checkpoints)
Is there a better way than to deal with this with bruit force? Oh I'm sure
The ones making trouble causing this police line to form every night are opportunists. The ones sitting atop these armored vehicles are our family, our friends. Do they make bad decisions at times? Of course don't we all?
Until the inner cities are safer then this will continue. I already laid out my view of why this is this way.
No offense (I respect you and your views as well) but your claim of "It getting worse" is just another example of "lock your doors because you will get robbed more TODAY" "Don't let your kids play down the street out of sight because there are more cases of rape and kidnappings TODAY" None of which is backed by facts
