Brazil to shoot down drug planes

From BBC News:

Brazil is close to adopting a plan to shoot down aircraft suspected of carrying narcotics over the Amazon jungle, the government has said.

Colombia and Peru called a halt to the controversial practice in 2001 after the Peruvian air force mistakenly shot down a plane carrying missionaries.

… Colombia resumed shooting down suspected drug trafficking planes in 2003 and has shot down almost a dozen planes this year alone with intelligence assistance from Washington, AP news agency reported.

Peru is seeking to restart the policy.æ

Sad.
Why can’t we force planes down, or, failing that, use our technology to follow them, and arrest them after they land?
Perhaps the better question is… “Why do we continue policies that make smuggling so profitable that they’re willing to chance being shot down?”
