Re: Wrongful Search by a Fire Department
are you being prosecuted by the military? and what is the charge?
but for sake of an answer; the (US) police can make entry of a housing unit by force if there are exigent circumstances. If they believed you were inside and had intentions of harming yourself and had not answered the door, their entry was legal. Evidence of illegal acts discovered during a search for you would generally be admissible. If they are required to apply US law to the situation, then it sounds like it may be legit. If they rules of evidence of Germany apply, you will have to find those.
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
