MSP ain't all it is cracked up to be, got the teeshirt and I am glad I switched to private HEMS for many reasons. About 3 years after I quit they put one into the ground and my buddy who was a Trooper Medic got killed, along with 2 other crew and a patient. What they did after the crash made me realize I made the right choice by leaving and going civilian HEMS. You really have to assess what you want to do, because very few places do both LE and EMS work well. The MSP medics are MD Paramedics with RSI, that is all. Now with almost every jurisdiction in MD having paid ALS the work is often done when they get there and they are a transport vehicle. In my opinion they are over utilized and do not provide a higher level of care then the regular EMS units, meanwhile higher level of care private HEMS aircraft are often closer and not utilized due to the monopoly MSP has on scene missions. They do some LE work, and even fewer hoist missions. Some of the guys moonlight as STATE team medics as well (MSP's swat team).
As far as BORDSTAR goes, I believe you have to be bilingual to work for them because I looked into it at one time. I may be wrong about that.
I would decide what you're interested in MORE, Law enforcement, or medicine, and then let me know and I could give you some potentially better options.
