Where did I say that all these people are assassinating police officers? I'll help you out. I never did. We do have Dorner's example. When he shot those cops they were baffled why neighbors never reported gunshots. The reason they didn't? Take a guess...Silencers.
Make these things ubiquitous will mean they'll be used more and more often in crime. Does anyone not agree with that? If so, please explain.
