That sucks, man. I had my place searched illegally, but unless you're ready to pony up tons of bucks for lawyers, court fees, appeals, the ends do justify the means for these over-zealous cowboys. They know that it takes greater effort for you to fight it than you can afford in time, money, and reputation.
It's all about money, it has nothing to do with what's legal or not.
