Recently several local news stations have investigated crooked contractors and they have been arrested. 

A lot of undocumented workers were arrested, but the plant itself was not charged even though they had recruited these people.

I began making my mission that every person I would arrest or put in handcuffs would genuinely smile at some point and by the time everything was over that they would say ‘thank you’.

this is in our lease regarding prohibited conduct, aka violation of the lease, "criminal conduct, regardless of whether or where arrest or conviction occurs, including but not limited to: manufacturing, delivering, or possessing a controlled substance or drug paraphernalia; engaging in or threatening violence; possessing a weapon prohibited by law; discharging a firearm in the apartment community; or, except when allowed by law, displaying or possessing a gun, knife, or other weapon in the common area, or in a way that may alarm others"I'm no lawyer but the person who wrote this lease is a lawyer, "regardless of whether or where arrest or conviction occurs" leads me to believe that suspicion of illegal activity is enough.

Quote from @Dewanna Kowalski: An arrest has finally been made! 

When I’m done with the physical part I call the cops and have them arrested.

But she’ll end up arrested for assault or something and he’ll go on his merry way.

They had moved my tenant out and into one of their other properties because the neighbor was harassing the tenant to the extent cops were called and property management had a warrant for the neighbors arrest.

Usually you need to give notice and then if they do it again they can be arrested. 

If the neighbors know you are putting a dog in a vacant home, you'll be reported to the Humane Society (and rightly so) and probably arrested...not to mention that's cruel to the dog.All of these solutions cost money, and cumulatively at least as much as you are losing as an investment.
