By the Parish. They supply everything for us. We previously had Crown Victorias but I like the Explorers a lot better. The department also has some Tahoes and Dodge Durangos but our unit uses the Explorers. There are still a few of the Crown Vics in service but when they hit 150,000 or so they replace them. The department has a full service garage with state of the art equipment to maintain all the vehicles. Also, boats, all-terrain vehicles, high-wheel flood vehicles and a semi-tank like riot control armored unit!. Ready for anything! We even have our own set of gas pumps and access cards. When the units get a little dirty we just pull up and prisoners wash them inside and out!
The dept. has a special Drone unit now, and it is very useful for tracking suspects where it is difficult for officers or even dogs to access. I just saw a video a Drone made this morning showing the path of the tornado for several miles. Looks like a giant mower cut a path through the trees, and unfortunately some houses as well.
