Cops

Went through a police check point yesterday. They were checking drivers licences.
They gave no clue as you waited in line that you were going to need it. So you had to hurry once it was your turn.

I don't know about where yours is, but I had to hurriedly scramble through my bag that was on the floor of the passengers side to find mine. What would have happened if I kept it in my pocket? Its really hard to get out with belt and pockets and sitting!

What if my bag had been in the boot? (trunk, for you americans)

Would they have pulled me over to the side to check it?

What were they looking for??
