I didn’t say that I thought he used a handgun. The question I was responding to asked about a 21 year age limit. The only such limit that I’m familiar with is the federal handgun requirement. While some states could have that age restriction on long guns as well, I don’t know of any.
So far, I haven’t seen any information released on the number or type of the guns he used.
As far as I know FLA is 18 for long guns and 21 for handguns.
Kid should have been flagged as a threat, more so if there where mental probs and drugs
