I continue to appreciate all your suggestions. Thank you all so much
I would also like to let those of you that mentioned a 2nd language know that I am currently working towards becoming fluent in Spanish, Farsi, and Chinese, and have been working towards that for quite a while.
As for which branch of law enforcement, I am seriously considering the FBI.
And for a quick gun update: I went to the range on Monday and shot both the Glock 17 and SIG P226. I very much enjoy the SIG. It's extremely accurate and well built. I suffered no malfunctions with it. I went back to the range yesterday (Tuesday) and shot a few hundred rounds through the SIG, doing tactical drills and such. It was great.
That's all for now, though as I've said before, I appreciate all your suggestions since you all know much more than I do.
