> [@md-2000](#): > > Police cannot give you immunity or promise a lesser sentence (only the prosecutor can plea bargain AFAIK, IANAL) They can suggest they would charge you for additional crimes that they can claim ou have committed. This is absolutely correct. Offering a reduced sentence is one of the interview techniques I cannot do. Big no-no! After a subject writes out their confession there is a form that is read to them that they sign. One section says, in effect, “I was not promised a reduced sentence by the investigator”. However I can say things like “hey, I’m just charging you with this. If I wanted to be a prick I could charge you with this, that, and the other thing”. Notice that statement isn’t a direct threat to charge you with other stuff or that I will if you don’t tell me what I want to know. It’s just a reminder of how nice I am not to charge you with all the other little things you did in addition to the big thing. But none of is pertinent to the link in the OP. I don’t see any violation or illegal seizure in asking for a SS#. And until we find out what happens to those that refuse were kind of stalled in the conversation on it. --- _[View the full topic](https://boards.straightdope.com/t/info-that-police-can-collect-without-a-warrant/950331)._
