I'm trying to understand the legal aspect here. According to the report, he was arrested carrying a heavy bag inside South Station. Here's what I see:
1) A heavy bag is not enough for detention, let alone an arrest. Unless weapons were sticking out or he was acting suspiciously, then detention would have been justifiable. Switching hands when carrying a heavy bag is not a justification
2) He was arrested inside a transportation facility. As per federal law, transportation of legally acquired firearms is allowed. Now, if he was arrested outside the facility, that would be different but I am still going to point to 1: no cause for search or detention.
3) no federal charges were filed. This makes sense. According to the photos, most guns were not loaded and the ammo was in separate boxes. Heck, even magazines were not loaded. According to TSA, this is an accepted way of transporting firearms.
3) As someone had mentioned in this thread, someone had given police information on the guy's intent to distribute within Massachusetts. Unless the guy actually sold the weapons in MA, the intent cannot be proven.
Considering that the ONLY charge is illegal firearms possession(one per firearm), I half-decent attorney will get them dismissed.
That said, if this guy came here to do illegal $#!t, he should go to jail! What pisses me off is that police acted in such a dumb fashion that this guy will most likely go free. What if the next time he is successful. These guns will end up in the hands of some gangbanger in Brockton and someone's son/daughter/wife/husband is murdered? All thanks to the ineptitude of officers eager for a promotion.
