I don't personally own any guns. I have shot many at the gun range. They are fun to shoot. If I was into guns I'd probably buy one. Target shooting is interesting and fun. Also, as and engineer, I can see guns having an appeal for the mechanically inclined. Learning about how they work, how to make them more accurate, maintaining them, etc. is as interesting a hobby as, perhaps, working on cars, if one is so inclined.

That's my only answer really. They are great fun at the range and neat to own.

I can't seen any other scenario unless someone is crazy and has other motives. Those corner cases will find ways to cause death and destruction by whatever means necessary. The 9/11 hijackers used common knives to kill thousands of people. Tim McVeigh used fertilizer and a rented truck to kill hundreds and destroy a building.

This, and the underlying data is why I don't subscribe to the idea of "assault rifles" being the root cause of our problems. I think the data shows that the problems are far more related to drugs, education, social and economic root causes than anything else.
