Conneticut Shooting : More innocents die in a " gun free zone "

Yesterday a disgruntled worker in Manchester, Connecticut opened fire at his place of employment killing 8 and then himself.   A very sad incident indeed but not unique, Americans are no strangers to mass shootings in the last decade they have happened almost every year.   What I find very strange is that we don't seem to have any kind of plan to deal with these mass shootings and it's almost always too late when the police get there.   This guy was able to kill 8 people before the cops closed in and he took his own life. Had there been a sheepdog ( CCW permit holder with a gun ) he may have been stopped a lot quicker but we can't bring our guns to work, as with school, the post office etc because they are deemed gun free zones.   Perps know this and they always seem to carry out their rampages in places where it is more likely someone will not have a gun.   This is a flawed system that needs to be changed. Gun Free seems to mean " Killing Spree ".   The killer had said that he was being racially harassed at the job and it was not addressed. Whether this is true or not thats no reason to go murder your co-workers. He could have taken other measures. But he was probably mentally unstable and this pushed him over the edge.   If the racial harassment claims are proven and it was not addressed then the employer and union may have a sand storm coming their way.   My heart goes out to the family of victims and I hope that some how we can figure out a way to stop these shooting sprees. They are happening way too often.
