If you listen to the likes of Dane on this issue, you will know even less than you do now...because in his view, even if the Cops were negligent, it's still Klebold and Harris' fault, not the Cops who may have slaughtered an innocent kid.
However, I believe there is an alternative to your supposition that we disarm Police or get rid of them entirely...
Make them accountable for their actions in the line of duty, and make sure they are trained to a level commensurate with said duties.
Which means if you are SWAT/HRT or the like, you qualify WEEKLY at a certified range to keep your skills at optimal levels.
Which means you PUBLICLY expose incompetent Cops and Management that are Political cronies of the corrupt Civilian Governments.
No more OMERTA, no covering for Donut-Eaters so they can get their pensions. Police are Public Officials, but WE are their bosses. This has somehow been lost in that last years. They are to UPHOLD laws...EQUALLY!
That is all we ask, but as I have argued with Dane and his LEO-Uber-Alles crowd, they seem to have a problem applying the same laws to themselves as we have to obey.
I'm sure someone soon will pop up with the canard of "How tough the job is", or "I am a Cop-Hater"...any takers on the over/under?
