Inserted on police

Yesterday, returning from work on the bike. The citizen in the form of riot police asked him to drive. We have in such cases refuse is not accepted, I drove up, then held a dialogue:
 - Good afternoon, Officer XXX, bike registered with the police is?
 - No
 - Do you mind if we will register? Suddenly, God forbid bike is stolen, it will be easier to find it?
 - No, I do not mind, let's register the.

Further standard questions: model, year, frame number, name of owner, etc.

 - Here's a sticker, if you want you can stick on the bike. Godspeed

It was all very friendly, drove other cyclists, all recorded.

P.S. Belarus, Gomel.
