No, you must be a bit dense if you can't see that the state does not want to murder someone in error in the same way that the state does not want someone to be killed in a road accident.
If either happens, it is a risk of the relevant legislation.
If you aren't going to stop people driving, why are you so keen to stop people using AD if they want to?
Is a someone who is killed in a traffic accident not as valuable as someone who is is assisted to die in error?
And who is to say that anyone will ever be assisted to die in error? They probably won't be, but we know that thousands of people will die in road accidents every single year, but you seem to be ok with that for some reason???
