But no one had a float to throw him?

Cop cars generally don't come equipped with floats, ropes or grab bars.

As for jumping in to save the junkie, no fully clothed cop in their duty uniform is going to jump in a river to save a guy being pursued. That's suicide.......

Never even suggested they should jump in.

But a rope or strap is common equipment in cars. I have both in the car and in the truck. You never know when they will come in handy. I would be very surprised if the police do not have a rope of some sort in the car. If they don't, they probably should.
