Nothing to laugh about

Every inch of those hotels are generally covered with video feeds. Every hallway is monitored. Just how would a second person or shooter exit the premises undetected?

No chance IMO. They can look/see every person that entered or exited the room.
Agree 100%, if someone else was there, they're on video........who is going to have that video in their custody exactly? I think the prevailing problem I have are definitive
statements by some before there is even enough time to have investigated the scene, again, who has that video & how quickly was it obtained & reviewed? The PoPo are
going to be on it, are they going to "edit" portions before anyone else gets to see it, even for some legitimate operations reason?
