hey i was wondering, how many killers have B&B caught and how many people has booth killed?

i just wanna know cause, i was watching the pilot and a line by booth at the end sort of was stuck with me. he was telling bren that he was once a sniper and he wants to balance out the number of people he killed with the number of people he catch. sort of to repay.. (or something along those lines.)
it would be appreciated, its just been bugging me...
