Changing my major?

[Dunit35]

I've been thinking about changing my major for the past couple weeks now. I've been in college for two years and came in wanting to be a history teacher, but I've really been thinking about changing it to Criminal Justice. I've always wanted to be a police officer. I've got some questions about all of it though. I feel like I'd enjoy being a police officer more then a teacher.

I've been wondering if it's even a smart to change your major two years into your schooling? Basically I've gotten just about all my gen eds out of the way with a couple of my history classes done too. So those history classes would be a waste of money. I go to a four year school right now and plan on transfering to another four year program in Oklahoma City. I've also wondered if it would be better for me to attend a two year program to get my Criminal Justice degree? I am wondering if I can actually switch from a four year school to a two year program? I know that a CC could be a lot cheaper for me too. Does anyone know how long it takes to get your police officer stuff done?

Thanks
