Later at the bar, Indy points a gun at Belloq. That's assault with a deadly weapon, and Belloq's lapdogs are all witnesses. We'll ignore the fact that Sallah should go to jail for life for sending his children into the middle of a Mexican standoff to rescue Indy. The children are our future, dude. Verdict: CRIMINAL.
The following day, Indy trespasses onto an archaeological dig that is so massive that it must be authorized by the Egyptian government. Which makes his entry into the map room illegal, and his removal of the Ark of the covenant very illegal. Also, wasn't it, like, totally safe where it was? Would the Nazis have even found it if they hadn't seen him digging for it? Then, when they lock him inside the Well of Souls, what does he do? He smashes the place up! "Fuck history -- I'm pushing over this giant bird and busting open that wall!" Can you say "destruction of state property"? Despite the whole self-preservation thing, his disregard for the preservation of antiquities makes him no scientist. Verdict: CRIMINAL.
Now, the next 20 minutes or so involve a lot of destruction of Nazis and Nazi property, so we can't really blame him for the guy he punches into the plane propeller, the truck he runs off the road or the dude he runs over. But we can blame him for the melon cart he obliterates, the irrigation system he destroys and the construction site he drives through. One worker landed safely on the truck's hood (he could totally pick Indy out of a lineup, by the way), but we bet the others landed on pointy rocks and sticks. Of course, it's not like he was in full control of the vehicle most of the time, even if he did really look like he was enjoying himself. And the Nazis had the Ark! He had to do it! Verdict: SCIENTIST.
After that spree, Indy lays low for the rest of the film, hiding on boats and submarines, borrowing clothes and a bazooka from the Nazis, and spending the climactic scene tied to a post. He even turns the Ark over to the U.S. government at the end, which raises the question -- since he was working for the government the whole time, can any of his actions be labeled criminal? Yes. Yes they can. If he'd been in America, he would have been a deputized agent of the law, but operating internationally (and not during wartime, mind you), he's what we in the blogophere like to call an "international incident waiting to happen."
Raiders of the Lost Ark Verdict: CRIMINAL.
