Here are some simple questions for "John Q Public" and our Politicians. First, why have "none" of the mass shootings we've experienced over the past several years been committed with a fully automatic weapon?
And secondly, what would be more deadly in a crowded environment such as a shopping mall; a "field of fire" laid down with a fully automatic weapon or a designated target for each individual round from a semi-automatic?
Obviously "weapon control" of fully automatic weapons requiring Class III FFL is effective, even though it violates our 2nd amendment.
P. S. When you put it in perspective, these weapons with large capacity magazines are even "deadlier" than the two bombs set off at the Boston marathon!
