Jerome Finnegan, Bad Guys, and Mexican Justice

Passing through O’Hare and the Sun Times headline is ‘Good Riddance’, referring to a Mr. Jerome Finnegan. Jerome was a Special Operations Section cop, assigned to undercover beats in bad Chicago neighborhoods. I can’t pass judgment on Mr. Finnegan, but he did get in trouble for putting a hit out on a fellow cop who turned government witness. My gut tells me he probably was a net positive for the average family in his jurisdiction. But the headline is ‘Good Riddance’ and Mr. Finnegan is now officially Mr. Bad Guy.

The road through Mexico to Central America used to be dangerous, with roadside hold-ups common. As Americans started moving to the Mexican Coast and the Mexican government realized the value of American pensions to their economy, the decision was made to end the hold-ups. A trusted acquaintance explained that the Mexican security folks knew some of the robbers and took them away, shot them, and dumped the bodies. Those who weren’t killed got the message. Voila! Safe roadways.
