Mind control cant save you from a gun, and remember, mind control isnt something that you just do and forget (no pun intended). It follows two rules (maybe more):
1) You have to have CONSTANT focus and control over the person's mind. Oka, maybe you can do that and keep your mind on what youre doing iwth one guy. Now lets say you're stuck in the middle of a gang, thousands of guys. You gonna mind control ALL of them, at the same time, exerting all the mental strength required, while having your mind focus on your body too? I somehow doubt it.
2) it will wear off. That means that at different times, since you didnt just mind control everyone at once. Also, you have no idea when it will wear off, since the stronger the mind, the less time they'll be under control. So lets say you fall asleep, and the control wears off. Guess who's screwed.
Also, you're talking about radius, and thats gonna exert energy. You could kill yourself just trying to control someone, especially if they can fight back (center a piece of their mind away and defend, keeping some free thought that can be later called upon).
Best superpower is time control mixed with an incredible sense of intuition (spidy sense). you know if I sniper fired a bullet at you from a mile away, can freeze time, move, go the person and kill them.
