Well at least they notify first.

US police would just start beating you and throwing you into pens, if you are lucky you won't get coated in pepper spray or hit by a sound cannon.

Watch the DNC and RNC conventions next year for examples with their multi-million dollar taxpayer funded "security".

But I guess this indicates police everywhere can now just record the phone numbers of everyone in the area to mark people for "watching".
