yes and no. - even the lowlife rogues can demand cargo - but that doesn t mean the victim has to comply. - bhg can demand cargo - they have no right to engage a smuggler if he does not comply though .... unless authorized by the local police ( not military ).
however, a smuggler is hardly informed about if a BHG is authorized or not - and at the point of a gun, some decissions are easier than others.
if a BHG knows he is not authorized, but he can still prove that he was upholding the law - he might still not get into trouble if his actions are not wittnessed by a police officer, - cause what does the smuggler want to do? - complain about loosing a cargohold of contraband at the next police station and ask to get his cargo back?
a smuggler that is stopped by a BHG should make his decission very carefully. - the BHG is not supposed to be very sensitive when it comes to dealing with criminals. - if the police wittnesses a BHG that is not authorized - they may tell him off for it.... but that does not help the smuggler much.
( server reality is sometimes different, i have seen police yelling at the BHG and even attacking a BHG that demanded cardamine cargos to be dropped. - in the meantime the smuggler went on his way while the police engaged the BHG [ silly world sometimes ]. - thats an example of false priorities )
either way, the smuggler is toast if he does not comply when caught. for the smuggler it doesn t matter if he is blown up by the police or the BHG - and knowing that the BHG gets yelled at won t do him good..... as a corpse in space.
