The 4th Amendment
No problem, get a search warrant from a court.
Let me break it down for you:....
You see apparently, we're supposed to have 3 branches (Executive, Legislative, Judicial) of government that have checks and balances for each other, so one can't overstp the other...the people that figured this system out
knew from history how easy it was for a lone branch to go
coocoo for cocoa puffs when an opening was made for complete power. So they put those checks and balances in for a reason.
In your lone wolf scenario the Executive branch wants/suspects shenanigans, its supposed to go to the Judicial branch to get the authority to go beyond the 4th Amendment. Its not rocket science, its just American civics.....
you don't know/remember history or civics........its ok...it not your fault (completely)....most our fellow citizens have fogotten/don't care how the system is supposed to work either...
