Surveillance Evasion Techniques

Wouldn't that make them invisible to the police?

No problem! It's a very good strategy, it's what someone who wanted to remain anonymous would use.

Could this done in order to cover the tracks of some illegal activity like a bank robbery? Seems like something out of Ocean's 11.

Not a foolproof method I would trust if I had something to hide from the police.

Then don't get caught, oldest strategy in the clandestine operations handbook ;)

You could also put on a disguise, sell something valuable at a pawn shop, then report it stolen.

they would probably still fake their identity to hide their tracks.

I think a great way to deal with this problem in a hacker type of way would be to create and post schematics for a cheap device (e.g. using your old cell phone or other types of old consumer electronics devices) to detect the presence of these devices. A big motivation of using these covert devices is that they work, i.e. the average tracked person is unaware of them. If this fact can be nullified, then law enforcement people may be less willing to use such tactics.

That is really good information! I would look a bit weird but it is discreet and no one would know the true purpose or make the connection.

You are going in the wrong direction. Lean into the surveillance. Use it to create an alibi.
