From Bill Formby at MadMikesAmerica:
Look, I know that everyone in this country is not a cop or a criminal justice junkie but there are certain people who do certain things, that they should understand certain things. For example. if you lay your phone down at a fast food restaurant while you go get a refill on your drink and you come back and it is gone, well, yes you are stupid, but that’s not my point. My point is that you don’t call the police and tell them you have just been robbed. Why? Because there was no damned robbery.
See it is like this. Terminology in the world of cops and robbers is really important. Robbery must involve either force or a threat of force which actually makes it a violent crime as much as it is a property crime. Police tend to react somewhat differently to your complaint of “I have just been robbed” then they would if you called them and said I was an idiot and left my phone on the table and someone stole it.
Granted, it seems to be the same to you, but not to a police officer. To the police officer, someone has just forcefully taken your phone from you or threatened to do you serious bodily harm if you did not give them your phone.
