My solution is this: If the police suspect that there is major illegal drug activity at a residential location, what they do is get a warrant, then wait until the middle of the night but late enough so that even most druggies are asleep, like maybe 4 AM. Just so it's still mostly dark. Then simultaneously (and quietly) shut off the electricity, gas (if any), and water. Then announce by bullhorn and allow the people inside a (short) chance to come out peacefully. If they try to flush the evidence, they only get one flush with the water in the tank, and that isn't enough to wash everything all the way to the main sewer line. (Trust me, I've learned this the hard way with sewage problems.) They can't even run the faucet. Plus, with the lights out, the druggies won't be able to find all of it quickly. Unless they only have a very tiny amount, there will be lots of evidence. If the police have to come in to roust them out, they will have the advantage of being able to control their spotlights and illuminate what they like, then when things are in hand, they can turn the lights back on.
In my mind, this idea certainly tops smashing down the door and hoping for the best. It minimizes the chance of killing an innocent victim at the wrong house while preserving most of the evidence even in the worst case.
The point of this thread is alternatives to racing in and waving guns in peoples faces.. Something the Libertines always bitch about.
So, by all means.. Alternatives are welcome..
That is a very very good idea !!!!!!
