Did the LV cops make all those commands? If so it sounds like a real cluster f###.
I was just illustrating the extreme of a potential problem, of obeying conflicting police orders, when acting, or *not* acting, could get you shot. This is not a good place to be, as officers are supposed to take the arrest initiative in such situations, but assembling quickly, none of them, and so, all of them, were in charge.
There is also a little confusion in the article, but I think that these were indeed LVPD, because Summerlin is not a municipality, but a planned community.
“Summerlin lies within both an incorporated municipality and unincorporated area. The area north of Charleston Boulevard is within the city of Las Vegas, while property south of Charleston Boulevard is located within unincorporated Clark County.”
The Cosco is located north of Charleston Boulevard.
