I LOVE your career choice!!

I went to school to be a cop. Right now there are very few full time police officer positions, so I have been applied to Hennepin County (which is Minneapolis) and Ramsey County (which is St. Paul) in Minnesota for a detention deputy- someone who works in the jails. Anyway, my point is that there are TONS of options available if there are no cop jobs available, and they will give you experience, too.
I don't know the exact situation of PA's job market, but police officer jobs are incredibly difficult to come by right now in the midwest. And it is a very competitive market. So I would advise that you gain some sort of experience NOW! And while you're in school next year. Join the police reserves for a local department. It's volunteer, but it's just 10 hours a month, which is doable for most people. Or Community Service Officer jobs are good experience too, and it's paid, but not high pay, so that's not always a good option for someone with kids! But I can't stress enough how important experience is!
I'm not sure how your police academy works there, but here we have two years of school, and then four months of "skills", which is full time 8 to 5, Monday through Friday, for the full 16 weeks. There you become licensed to carry a handgun and you learn how to fire properly. You also learn how to make proper stops and arrests, etc. At the skills here, there is an entire week devoted to making a DUI stop. You also learn all the equiptment in the patrol cars. And then after skills there is a POST test (Police Officer Skills Training) and when you pass, you are finally able to become a licensed police officer, assuming there are jobs! LoL!! It's a tough, tough market right now. I think you're getting in at a good time because by the time you are done with school and Skills training and test taking, the market should be looking up! Way up!
The other thing that they don't always tell you before entering school is that you have to have a nearly flawless background and good credit. I'm sure your background is fine, but I'm just throwing that out there.. My professors advise us to go to the BCA before we get too far into the program and request a record of our own backgrounds. Then you can know for sure what exactly is on your record, and you can find out what will automatically disqualify you. Here in Minnesota, too many speeding tickets will disqualify you! (I'm worried about that for myself!

) A DUI within the last 7 years also disqualifies you right off the bat, as well as domestics, or any type of assault at all, any kind of possesion, etc. So it can be really touchy.
I also have to add that the stigma of the job is worse than the actual job!! The number of police shootings is soooo low! But when it does happen, you hear about it right away, and the media really play it up. If you're worried about working in Philly, apply elsewhere! You don't have to work in the city in which you live.. actually, they encourage you to apply outside your own "home". I can't STAND it when people diss my career choice because I am a woman and I have children. That drives me absolutely NUTS! I have a better chance of being struck by lightening than being killed as a cop. This is based on the percent of all cops being killed on duty compared to all people living in the US who were struck by lightening. Not good odds! I worked at the Homicide Research Center in Minneapolis and there was a study done that showed that citizens believed that cops were over a 1000 times more likely to be killed on duty than they actually were! There were only two police shootings in Minneapolis that year, and neither were fatal. And two is HIGH!!! Most years there are zero.
Anyway, I could talk forever about this stuff! If you have any questions you can PM me if you want! I'm sure I will think of more and come back to post later! I love this topic. I originally went to college for Spanish, and then went back for Criminal Justice to be a cop. When I was in school for Criminal Justice, I have never enjoyed myself so much! It's awesome if you love what you're learning!
