That consequence (assuming they had no legal reason to be on the property) generally is a suppression of the evidence. While they may have done something wrong, or even actionable, it does not automatically mean that a civil suit is worth anyone's time or money. This is why you need to consult an attorney. If they ask for a few grand up front, you know that it may not be worth the effort.But even though I may look bad. The Police should suffer the consequences for not following the law.
Start with the phone book. But, attorneys do not work on contingency unless the payout is likely, and is sufficient to make it worth their time and effort. If the case will be long and/or difficult, and the potential award is either iffy or small, then you will not get a contingency agreement.Now how might I find an attorney that would be willing to work with a contingency fee?
