OK, NOW I smell a rat.
Let's assume the following are all true:
1) The door the cops eventually went through was barred (reported but I've seen no pictures confirming this...).
2) The cops were fired on BEFORE going through the door, while approaching the house.
3) The cops shot at (or shot) were part of the "first on scene team" rather than a second wave (arriving backup).
The above doesn't make sense, because without support from flash-bangs or the like from 40mm launchers, there is NO WAY any modern police department is going to attempt to defeat an armored door while under fire.
Follow? If they hadn't yet defeated the door and they came under fire, they would retreat. Doing otherwise would be suicidal...they'd be stuck immobile at the barricade point (the armored door) while under fire. Not conducive to survival.
So: IF the door was armored, and I want confirmation, I would say it would be impossible for a first response team to get shot BEFORE defeating the barricade yet continue the attack and kill granny.
Way more likely they defeated the door and then came under fire.
I wasn't even going to comment on the pot, except...it's possible that this incident could lead to legalization of the drug, in Georgia or elsewhere. If law enforcement is going to seriously use small amounts of pot to justify killing a granny, then to me that's the absolute last straw as far as prohibition goes...no such "excuse" can be maintained - or allowed to stand.
We're reaching a point here where honest, otherwise law abiding citizens start to realize that the "war on drugs" is a war all right - on all of us and on basic concepts of civil rights.
