Here's the thing about the police amphibian unit. They don't get to be used a lot, but when they do... they totally screw it up. Obviously the police amphibian unit isn't a real thing because that would be ridiculous. Almost as ridiculous as these guy's plan. Did they really duct tape the front grill to protect the engine from water? They didn't realize that there are hundreds of other ways for water to get in? This is dumb people trying to be smart. If you're a dumb person (and trust me, you should know if you're a dumb person), and you think you're doing something really smart, back out immediately. The chances that what you're doing is actually an intelligent idea are very slim.
This is where your tax money goes, folks. This sixty thousand dollar truck got fixed with our money.
