Can someone call the cops on someone and accuse them of doing something and then the cops keep am eye on them?

Let's turn to commonsense to answer your question. *Puts feet up on desk and emits a condescending sigh* Anyone can call the police to make accusations. The police have an obligation to discern if the accusation has any merit. If they believe there is merit, they are within legal bounds to check out the party that has been accused. Note that the accuser could also fall under surveillance.

It's at the police station's discretion. Either way, probably good to have these concerns on record sooner rather than later.

No lol

Google, Facebook, Government, The Apps On Your Phone, The Phone Itself, Smart Devices, Let's just say everything that connects to the internet, telephone, or satellite is watching you, them and everyone else on the planet.

There is no more privacy like there was when I was born in the 60s.

They know everything you, everything you type, every location you ever have even been and your exact location right now. They know your friends, your doctors, what drugs you're on.

You can't even poop sideways without them knowing.

That's harassment

Happens all the time. What matters is who's the one doing the accusing and who's the one being watched.

People can and some do

Cops dont actually have the manpower to just "keep an eye" on someone simply because some snitch told them to. It has to be worth it for them and something in it for them like a huge drug bust or an arrest. Sure you can put someone on their radar.

nope, unless it's a concern for public safety and you have some proof

Lol…… afraid you’re being watched by the cops?

That's a good way to get yourself arrested for abusing law enforcement resources.
