This is a video from the concert that caught flashes coming from the 4th floor....
The shots in the video were going on when the shots were heard....
The noise is off by a little bit but the distance fits the delay....
Watch and you be the judge....
Not saying it's a false flag until more news comes out but someone caught this on video and it's worth a look....

Regardless....my condolences to those who lost their lives.

It's unlikely in this case. The weapons used were fully automatic machine guns, which most people could never own in the first place. Only millionares can own guns like these. They are much too expensive for most people, and require a full federal background check before you could even have the opportunity to buy one.
