we all know about no knock raids in the middle of the night, where the feds would use night vision goggles, so i had the idea that you install some heavy duty flashlights or similar lamps that use batteries or that run on a seperate electricity network so that they still work even if the feds cut the phone and elecrticity wires, install these lamps in place where you know they have to pass through to reach your position (a hallway for example) and use a tripwire or a voice command or some other kind of device to activate the lamps (depending on your budget), depending on what you use plan accordingly, and shortly before the lights are activated swap your own night vision goggles for a type of polarized glasses (normal polarized glass should do the trick, alternativly specify the glasses to your needs) then activate the lights, this should blind the feds for atleast a short amount of time which should give you enough time to either eliminate a few of them or change your position and make an escape if you have been compromised
