I had the same thought. These types of trips should be cleared with local government, so who knows what is going on in this particular case, but if they were on an outreach trip (what else would they be doing?) it is a shame. It gives all outreach trips a bad rep. These trips do allot of good, that government is crazy. Bad indeed.
I signed up for a global health outreach trip for over spring break. I will know sometime in the first week of October if I was selected or not. Hope this kinda thing doesn't happen to us!
