Yes, I can.
First of all...[Technical difficulty—Editor]...500 feet per second, 495 feet per second, is an accepted world standard. Virtually every country in the world says that if it's over that, it's a firearm and if it's under that, it's a BB gun. Even in places like England, where firearms are virtually banned, you can still purchase air guns below the 500 feet per second mark.
I can tell you, sir, that the negligent storage of anything is already a criminal offence. You can be charged with criminal negligence should you leave a loaded BB gun in a place where a child could get it. That doesn't have to be enshrined in law. It's been there for many, many years already.
