The OP's question has not been answered. People have told the OP that the DMR digital standard will work just fine, but I think he was asking more specifically if a XPR DMR radio can take the same beating as a APX, or XTS 5000 radio. To me the answer is no way. They are not public safety radios, and not designed for public safety. It's usually cash strapped small entities who can not afford to buy APX6000/7000/8000 radios who buy them. So the proper reply would be if an APX, or XTS5000 could do DMR, then yes, DMR would be fine for LE. There's a reason a P25 radio costs 10 times what a DMR radio costs, & it's not the digital standard. An APX, or XTS5000 can be run over by a car, & still work. That won't happen with a DMR radio. Around here a DMR HT wouldn't last a week in LE service. Maybe in Podunk Iowa it would.
