You guys are basically arguing over your risk tolerance for admitting a terrorist into the country. The libtards are happy to assume the risk (it is rough ridin' insane to argue there is no risk, so stop it), because that's what their master wants. The normal people prefer to error on the side of caution. Railing against each other over risk tolerance is stupid.
What you are all missing is that these people will likely be monitored by the DHS for the rest of their lives, like some enangered species. Without permission or knowledge. That seems mumped up for the non terrorists.
