It is less likely that they might be subject to impulses to whack somebody on the head. Paradoxically, they would probably be rather inclined to behave themselves in a fairly prim way to avoid being caught. However, as well as exposing passengers to potential danger, not just from the actions of the driver but also from attacks by other gangs, it provides an apparently legitimate cover for criminals, which is not acceptable. While I welcome the Bill, I suggest that the question of the level of involvement of former criminals be examined. It is unfair to decent taxi drivers and passengers.
