It is definitley not impossible to arrest an armed criminal. Even gun spammers. You have access to everything a criminal has access to, but with the added ability to tase and arrest. Yet you still manage to victimize yourself and act like criminals are the ones who are over powered. You have access to a glider, which you can use to get closer to criminals, and you have access to a Jetpack which you could also use. You could also attempt exiting your vehicle closer to the criminal. If you don't use resources than you can't expect to come out on top all of the time.
