IMO, on July 12 a SWAT team executed a search warrant at CWW's trailer. LE likely intended to find
something during the search that would support probable cause to arrest, so they were probably waiting on an arrest warrant.
It all depends on the circumstances, how to ensure the preservation of potential evidence and officer safety. Here, because they used a SWAT team to execute the search I feel confident saying LE took extra safety precautions for a reason; CWW's criminal history, potential for violence. I'm sure they were worried if they simply asked CWW to leave the home, he'd 1. flee 2. destroy evidence not in the trailer 3. kill himself or others. Also, given CWW's background, who is to say he wouldn't go to a friend or family's home and remotely destroy evidence.
I wouldn't be surprised if they used a "flash bang" instead of knocking on CWW's door. Let's
hope that CWW experienced a mere fraction of the terror TS experienced on June 29.
"The flash bang creates a diversion by emitting a loud bang and a flash of fight," said Sgt. Don Brown, who is the assistant commander of the DeKalb County SWAT team.
Only SWAT officers who are trained and certified to use flash bangs are allowed to deploy them. The bang, flash and the smoke give SWAT officers enough distraction and cover to safely make their move.
"If you didn't have this type of device, this diversionary type of device, you are risking - you are allowing the subject to be somewhat ready for your approach," Brown said.
