Friday link roundup

Stuff to read this weekend, perhaps on my flight Sunday night:

• Josh Marshall calls the MH17 shoot-down a mind-boggling screw-up of Putin's.
• So does David Remnick, but more nuanced.
• Chicago's infamous red-light cameras have suddenly started issuing massive numbers of tickets, and nobody seems to know why.
• A 2013 court decision has caused an increase in delays on Amtrak trains nationwide...
• ...which isn't helping their financial situation.

Now back to the mines. Which, given the client I'm working on, isn't far from the truth.
