Pointless conjuncture.

If you want to make this argument, you can at least provide some data on how much some police departments make by collecting seat belt fines, and compare it to other fines and cost of operation. I doubt the seat belt fines are significant enough to warrant this speculation.

The airbag argument is even worse. Modern vehicles go through numerous safety standard tests, including real world experiments where test dummies are put in an actual car crash. If seat belts make the crash worse for the dummy than airbag alone, these tests would have shown it, and there would be publications about it in a peer reviewed science journal. If you are so confident, you should be able to find at least one such publication. I doubt you will.
