The AP reports that a border agent disregarded a warning on TB infected Andrew Speaker - the TB infected, ethically challenged, globe trotting lawyer from Atlanta who endangered the health of untold numbers - was not nabbed by a border agent, despite computer warnings. Apparently the agent felt the man appeared healthy and that the warning was "discretionary". The guard has been removed from border duty.
Certainly this doesn't increase anyone's confidence, especially with the outrage over the lack of border enforcement as the Senate immigration bill is being debated. Will guards be "discretionary" with terrorists, drug smugglers, human traffickers, etc. who try to cross border?
