Kansas

It seems like it is extremely hard to destroy evidence, and, frankly destroying drugs doesn't seem that big a deal to me. Make sure all the exits are covered and send a robot up to announce that a warrant is being served if you feel there is a danger.

The thing you don't do is knock the door down to people who are sleeping or relaxing in their homes. They have absolutely no ability to process what is going on. Their dogs are freely moving around like any family member.
