"Police said they contacted Walton on Friday after observing a drug deal."

"The man arrested... faces charges of resisting arrest and interfering with police."

It seems he was arrested for resisting arrest, while officers were questioning him about an alleged drug deal.  However, no mention is made in this story about drug charges lodged against this man.  This is puzzling.

In terms of the arrest itself, the officers showed restraint. Did this man need to be stopped for questioning in the first place? He should have cooperated.  The crowd should have refrained from obvious hysterics. There was no blatant police brutality that I saw, only painful though non-injurious physical coercion.  

A lot of video was recorded. I think this will get straightened out.

But I have to say, I used to live near downtown and regularly walk at night.  I had some unpleasant encounters with young loiterers but nothing that got me worried.  Recently, doing daytime business downtown, it's menacing.
