"Moreover while the 2nd amendment provides the right to bear arms, common sense also should prevail but it doesn't seem to be happening."

I suspect you are not a gun enthusiast or gun sport participant or a member of the NRA or any number of other shooting organization. If you are, I am wrong.

As a gun enthusiast, active participant in many shooting sports, NRA member as well as member of several shooting clubs I am compelled to counterpoint your comment above. There are millions of gun enthusiasts, shooting multiple millions of every imaginable type of weapon and ammunition with an impeccable safety record. As with the clubs I shoot with the priority is ALWAYS safety first, and then have fun.

So my counterpoint is common sense does more than prevail in the shooting shooting sports/industry. The shooting community goes way beyond common sense in it's belief and practice.

If there is ever a violation it is very rare. I do not know the nation wide number but I can tell you the clubs I belong to for the last 55 years their safety record was and continues to be 100%.....no accidents. And I am sure that is more typical of all the organizations.

I don't know the details of those who carried what and where at the rally of subject. What I do know as Steve has very well explained, there was no threat or potential threat to the POTUS or the crowd.

How accurate the reporting is on the incident is yet, if ever to be determined.
However the individual(s) were obviously within their rights and within the law. Most of us gun enthusiasts and licensed to carry would vote they did not exercise very good judgment.

Legal gun owners and organizations in the USA are among the most responsible, safety and consideration for others people on the planet.
Like all groups there are exceptions.....they are statistically insignificant....even just one is unacceptable.
