"...elevating the alignment between security professionals and law enforcement."
An added rider on the contract along the lines of...
"In the event of arrest and/or legal charges in carrying out the contract, you agree to post bail, pay all legal fees and should this involve jail time agree to pay the professionals involved, directly, double time throughout their period of incarceration (calculated on an hourly basis) upfront, on the assumption no time off for good behavior is received. Hourly rate to be based on day rate divided by seven point five where appropriate."
That should cover the bare minimum.
