Police can they watch over your iPhone?

I got introuble with the police in the summer for a thing over snapchat IIm 13 and I live in Ireland my mam said to me that they re monotoring all my stuff and she said that they said IIm not allowed on snap chat again or they ll call back? Is my mam just saying this? Or are they actually help?

That would be the Govt who is listening and recording everything we say on our phones.

Could be so.

Yes everything the authorities and intelligence community monitor anything they can such as complications through media and even this online site y ahoo answers is probably being monitored

Your mom is lying, but it IS possible for them to do what she claims.
Note: ANYTHING that has been transmitted in your lifetime CAME be retrieved from an archive SOMEWHERE. It may be difficult to find, but it IS out there somewhere.

They could.

Police can watch over ANY cellphone when you're a suspect, no matter how old you are.

And, I'm an EU citizen, too, so, yes: They do it in Ireland.
