I completely agree. I had heard of the incident you mentioned but it's not the first time that near exact situation has happened and I didn't realize it was just this year.

My comment was mainly referring to large organized crime or violent gangs that would warrant a SWAT team. I've seen SWAT called in for college students because an undercover smelled marijuana. Who were they trying to help? The students that wanted marijuana? Didn't we learn our lessons about prohibition 90 years ago?
