Captain Carmine Fanzone is the apparent head of the Detroit police department. He hates machines, but in an "I'm old" sort of way rather than being evil or anything. However, despite his oft-repeated mantra of "This is why I hate machines/robots" whenever some device in his vicinity goes on the fritz (often with comedic, embarrassing results), he's pragmatic enough to make use of technology when needed. For example, he's a world champion at yelling at subordinates through megaphones for added effect. And firing heavy weaponry at rampaging robots.
Despite his endless battle with the march of progress and general poor luck, Fanzone is a good cop, dedicated to protecting the people of his city, even if he dislikes certain demographics. He's also not a bad guy to have in a brawl. He doesn't completely trust the Autobots, but he's at least assured that they mean well and, like him, are here to protect and serve the people of Detroit. He just wishes that they'd stop destroying so much of the city in the process.
Along with machines, he also hates lawyers and kids, but most of all, he hates tech support for machines.
