Why do police bikes have suspension? This may be a dumb question but why would police bikes have suspension?

They mostly all seem to have suspension on the front forks.

They're not going to be jumping off rocks or anything, are they, so what's the point? Doesn't suspension just make them slower, heavier, more expensive, less enjoyable, and higher maintenance?

I say that as someone who has never experienced riding a bike with suspension.

Doesn't Why top touring bikes have no suspension forks? suggest they're valueless? But that's implausible because they're designed and bought professionally; so why?
The main reason I've seen is that police bikes are generic mid-price mountain bikes, and those almost always come with suspension. Even when they're decorated and packaged as "police bikes", they still seem to start out as mid-price generic MTBs.

This comes from the requirement that they be reasonably rugged, able to have police kit bolted on, be reliable, and affordable. Most velocops don't have the budget to start with a $5000 bike and then modify it to work as a police bike. And it's very hard to find a $5000 bike that would be a suitable starting point. But it's also moderately hard to find a $1000 MTB without front suspension.

In Sydney (Australia) at times the velocops get to buy their own bikes, with the requirement that they be able to have all the doodads the police like attached. So we have seen some variation, from cops who put their own money in (or repurpose other budget) to get decent bikes, through to a bunch of "police auction" specials which were ok, but it was amusing to see cops with official bikes that had had the serial numbers filed off. Still, most of those were mid-price mountain bikes with front suspension, because they want the heavy frame to get a bit more ruggedness.
