i daresay that would be fine improvement in balancing if arrests would be less frequent, but failures be more frequent at the same time, even with more h/p cost.
the same would even better apply to assassinations - failure in assassination to result in wounding/serious wounding for attacker (did such feature exist before?!).
that would also provide some more fun for the to-be-victim, as now and than he could boast with his skills against assassins.
