Why did the policewoman Kelly call the inspector?

Kelly: We have just detained a suspicious-looking individual here in the Kilburn Road, sir, and just phoning in to see if you have had any reports about break-ins this evening because this man has got quite a lot of stuff in the back of his car and he is a bit, shall we say, nervous.
Inspector: Right, Constable. What have you stopped him for?
Kelly: Breaking the speed limit, sir. We are just giving him a breath test, and he is making it very difficult.
Inspector: Well, make sure that the breath test is a long one, Kelly, How do you know he’s got stuff? How much can you see?
Kelly: He is in a van, sir, with windows all around. You can see it all there on the floor.
Inspector: Have you got a list of what you can see?
Kelly: Yes, sir. Couple of color TVs, for a start, one big and one a small portable, couple of bottles of whisky, Johnny Walker, an electric sewing machine, new by the looks of it, two typewriters, one of them electric, a set of golf clubs.
Inspector: Good work, Kelly. I think it would be reasonable to suppose that your gentleman there would be able to help us with some enquiries we are making about a break -in earlier this evening.
Kelly: Shall I ask him to come with us to the station, sir?
Inspector: No, wait till the second car arrives. Then bring him in
Kelly: Right sir.
