It happens here, too. Once you have chased the burglar off your property, it is a different playing field.
We had an instance here in St. Petersburg a few years ago when a restaurant owner came upon a bad guy stealing the day's receipts. Bad guy ran. Business owner jumped in his car and ran down the bad guy causing him greivious injury. Business owner was found not guilty by a jury of his peers. But he was charged by the DA!
Another instance in Santa Rosa, California found a homeowner awakened by a bad guy climbing through his kitchen window. He clobbered the dude with a baseball bat knocking him back outside. He then went out and proceeded to demonstrate his displeasure by further application of the baseball bat to the head and upper torso of the bad guy. DA there elected not to prosecute but was quoted in the paper warning citizens that they cannot administer justice when the threat is eliminated. In other words, you can knock him out of your house in California. But you can't chase him down the street.
In Florida we have the Castle Doctrine that allows us to shoot intruders. We also have a "stand your ground" law that does not require us to run from a threat, but rather allows us to "deal" with it.
