Replying to Which Military Branch?

Well im at the middle of my Senior year in high school. And ive been somewhat interested in joining the military, pretty much only because its a job that will pay me and will pay for my schooling. Ive been talking to a Marine recruiter on the phone and in person and he took me out to eat the other night..but i just dont really like the way the Marines attitude is. I dont know how many newschoolers know about the military but i was just wondering which branch you guys would recomend looking into. Im looking to become a police officer after i get out, and im looking to get my college paid for. I got a 23 on my ACT, but my GPA is about 1.6 right now.
