After Having viewed the video, all I've got to say is:
This is unnacceptable.
Displaying this level of force for a couple of high school pot dealers is entirely over the top.
I'm not really willing to contemplate as valid the "officer's safety" argument, because that can be used to justify any level of force, in any situation.
Absent any direct opposition, when this much force is thrown around by the state, it has only one purpose:
To cow the populace into compliance.
We cannot accept this.
This is SO WRONG I CAN'T EVEN BEGIN TO TALK ABOUT IT.
What have they achieved with this raid?
Well, they didn't catch any pot dealers, and even if they did, that end would not be justified by the means.
What they did succeed at is scaring the crap out of a lot of kids, and taught them that the power the state holds over them is limitless.
Shame on everyone involved for their bad judgement.
