What you fail to realize is that rebels have better gear, weapons and typically more friends rolling with them then a bounty hunter. This is their one advantage and you want it taken away, just play smarter when you have a bounty. Everyone thinks it is fun getting a high bounty but then get mad when it does not end well for them, you want to be a rebel man up. If you let someone sneak up on you plain and simple it is your own fault, and besides if it is in a city you still have plenty of chances to be set free before you are arrested.
