The latest murderer whose name I, like the mayor of Las Vegas, will not use out of respect for the dead and wounded, had more than 40 weapons in the hotel room, in his car and at his nearby home along with thousands of rounds of ammunition and bomb-making materials. According to the police, each weapon had been purchased legally with the required background checks performed. This begs the question, how does one amass such an arsenal legally, many over a reportedly relatively short period of time, without it raising a red flag somewhere? Along with the weapons themselves, the killer also purchased about a dozen "bump stocks" which effectively turn a now legal semi-automatic rifle into an illegal nearly fully automatic weapon. How and why was this thing made legally available in the first place? On Friday, it was reported that the NRA and the White House have indicated a willingness to "consider" additional regulations on these attachments.
