If people wanted to kill they will find ways on how to kill. Those people might be taking drugs or have watching too much crime movies. To think that night clubs have security guards, how could someone enter that premise and just shoot. That nightclub should also be held liable for that shooting incident. This could not happen if they have tight security enforcement.
First and foremost they have to restrict the selling of guns,if not sociopath like these prop up in a crowded area and starts shooting people. This is not the first incident this month and this wont be the last. It keeps on coming, daily we would hear some public shooting.
when would the politicians open their eyes and put a ban on guns.
The places where the shootings were carried out were "gun free zones" (But not really).
