Every time I make a post I feel like your instinct is: he thinks we shouldn't have any guns! But that is so far from what I'm saying that I don't understand the reaction. Because of the propensity of weapons from the Federal Assault Weapon Ban being used in mass shootings, all I've said was that the type of guns available for sale to the public should be amended. And that's because in most cases, the weapons I'm talking about taking off the market are bought legally.
Here are some security guard articles I think you should read that demonstrate the dangers of arming security people that I discussed in the post you quoted:
