You missed the point, moron. And yeah, when the poster says "just obey the law", does it just mean certain laws? The examples are meant to be ridiculous. Just as ridiculous as pointing out "well don't break the law" when someone says that cops are acting like f-ing idiots and killing people. The point is... there are countless laws that exist and yes, many are more serious than speeding or selling pot, but a lot of these aren't serious enough to kill someone who is unarmed. So you clowns get to decide which laws that are broken deserve death, since it's just that simple as obeying the law, right? Get it now? Probably not.
I don't think it's being implied that someone that breaks the law deserves to die. The implication, IMO, is that breaking the law puts you in a negative situation that could potentially escalate. That escalation is dependent upon the law broken and how you react.
For example, if I am caught driving 10MPH over the speed limit, that is considered pretty mild. If I accept that it's my fault and take my punishment (ticket, fine, traffic school) without any grief, all is well.
However, if I am caught stealing from a store and decide to run from the police, things will escalate much differently.
Simply put, don't put yourself in that situation.
