You guys know about the bombing in Boston and how they caught the surviving bomber, but what you might not be aware of is Representative Greg Ball of the US House of Representatives advocating torturing the Dzhokar Tsarneav.
For more people saying we should torture Dzhokhar Tsarneav you can just check out the Twitter search (admittedly, there are a fair number of people opposed to it too).
Torture in this circumstance comes from two motivations. The more reasonable is interrogation. While Chechens are usually known for terrorism against Russia, the explosives knowledge and a choice of targets (a high-profile, internationally celebrated event with minimal security) might indicate some outside help. Certainly, applying pressure to get information on that outside help is going to be more effective than asking nicely. The beauty of torture is that you can ask nicely, then apply that pressure. Personally, I don' t think torture is very effective, but then I admit there's a liberal bias in a lot of my media feeds.
The worse reason is retribution. My fellow countrymen have an unhealthy attitude with retributive punishment that really ends with terrorists. We have an entire party that wants to punish people for bad life decisions and sees prison less as a place of reform and more as the expensive shelf to keep black people on so they don't clutter the place up. What I'm saying is that retributive torture is part of a long, bad cultural excitement over making certain people suffer.
Skipping over the topic of folks who allow no impairment of the second amendment while gleefully penning exceptions to the sixth and eighth, it's discouraging to have to remind people that we are supposed to be the good people here. The use of righteous outrage as a source of infinite justification for any retributive action is the action of the enemy, not of the self-purported leader of the free world.
