Because of course it has.
When it comes to police car fleets, Dubai has to have one of the most interesting in the world. All that oil money can buy some serious wheels for its law enforcement officers, and the state does not hold back. We've reported on all sorts of cars over the years joining the fleet. From Lamborghini Aventador and Ferrari FF cop cars to the Bugatti Veyron and W Motors Ghiath. It's reached a cartoonish level of overkill, and therefore makes complete sense that they would want a Tesla Cybertruck on the fleet.
According to Arabian Business, Dubai Police's Major General Abdullah Khalifa Al Marri says that the Tesla Cybertruck will "enhance security presence in tourist destinations, such as the Burj Khalifa, Sheikh Mohammed Bin Rashid Boulevard, Jumeirah Beach Residence and La Mer."
In reality, we suspect it's more for show than for doing any serious police work. We haven't seen any recent reports of people throwing metal balls at police cars either. Saying that though, if the Cybertruck makes it into production and uses the materials promised, then it should make for a great vehicle for security work.
Although Musk's demonstration of the strength of the Cybertruck's windows failed on stage, armored glass isn't uncommon, and the material used for the body has solid science behind it. We don't expect to see Musk pull out a Glock and pump some 9 mm rounds into a truck, but it's believable that the occupants would be well protected.
What spec Dubai police is planning to take delivery of its Cybertruck is unknown, but we would imagine they won't hold back. The Tri-motor system will make plenty of power, and the claimed 0-60 mph in 2.9 seconds is plenty to start catching up with lawbreakers.
