FBI banging down doors is a real thing
My nephew is a PFY. Lived in an urban area, and left his WIFI open. No big deal. Except some pedo down the street was using it for unsavory activity. The Feds showed up at my nephew's door as he was leaving for work and gave him 30-seconds to warn his wife they were coming in.
They had a valid search warrant and they searched his computers, finding nothing. The Feds started to suck up to my nephew, telling him how tech savvy he is, how he should be working for them, etc. Appealing to his civic duty they then asked to put a tap on his network for two weeks and told him not to tell anyone about the incident.
The only problem is, putting a tap on his network and a gag order was NOT part of the warrant! He should have immediately headed to the local news station and told his story. If that caused the Feds to lose their suspect, that is a problem of sloppy investigating and fishing warrants. Law abiding citizens should not be subject to law enforcement banging down doors and violating our private lives. This whole situation was clearly a government violation of the Fourth Amendment.
The tech issue is the open WiFi, of course. However, the Feds failed to explain to the judge that anyone within a couple hundred yards with a decent antenna could access it. Around 50 residences, including the Feds from their vehicle out in the street. The judge should have recognized this and then denied the warrant. The Feds simply had not done a thorough investigation...or they lied / left out details to the judge.
The pedo was thankfully caught. The ends, however, do not justify the means. One citizen's Constitutionally protected rights cannot simply be overlooked in the pursuit of Justice. Search warrants are not permitted to be served without establishing probable cause.
My nephew learned from this, and eventually understood everything that transpired. His WiFi is still open. But he now lives on property in the country. Anyone accessing his WiFi is trespassing and likely to get a 12ga welcome...including the Feds. I don't fault him for not trusting law enforcement after this experience.
