I watch a lot of ID TV shows. When the cops are describing arrests of criminals they watch the place and go in when they know the perp is there AND whether anyone else is in the home that could be harmed. I guess only murderers are apprehended that way, not petty drug dealers/users.

I guess only murderers are apprehended that way, not petty drug dealers/users.

Well, this wasn't a case of attempting to apprehend just a "petty drug dealer/user" . They knew that the perp might be armed. From my comment and the article to which I linked:

Law enforcement officials were familiar with Thometheva, who had prior drug and firearm related arrests.

Here's another article from AJC:
Terrell justified the use of the no-knock warrant by telling the AJC that Thometheva, of Cornelia, had possessed weapons including an AK-47 assault rifle, during a previous drug arrest. Random photo of AK-47.
