A Mandalay Bay valet said glass was falling on them, so it was the shooters blowing out the windows in hotel rooms. So if the shooters were isolated like that, no one would be able to hear them yelling alahu akbar.
But I surmise this is obama/soros/blm, and not jihad. This is the same situation as Dallas. Shots fired at white southerners, this time at a country-music festival goers.
Yes, the target selection (country music fans - predominately white & Conservative) made me think strong likelihood of BLM ragers.
