Awful I was at this club before . One of the reasons I hate going to clubs is they insist on disarmament. I never feel comfortable in these situations.

Christina Grimme likely would disagree with you, if she were still alive. The problem here was not too much security, but too little. Had the club been able to go into lockdown mode while the shooter was still outside far fewer would have been hurt.
Sadly, we're gonna get people from all parts of the gun politics spectrum trying to make hay out of this when the tragedy that needs to be most addressed is the thousands who die from guns one or two at a time.
