In general, most of us abide by the law for fear of consequence. As we know, laws don't always make sense, and not everyone agrees with them. Laws and penalties change from place to place - some places have strict laws against drug importation, some places give you a slap on the wrist. Some countries take different approaches to road laws in respect to speeding (Germany) and lane splitting (US and others). The fact that a law exists doesn't mean that it is valid to a society, or that it makes anyone safer. As an example, the US introduced prohibition in an attempt to reduce crime and health issues among many things. The law was effective in reducing health problems, but crime rose as a result. The fact that the law wasn't logical didn't stop it from being brutally enforced, and in turn it didn't stop many people from breaking it. The question has been posed (thanks hornet): Should we break laws because we don't believe in their objective, or break them with a view to having them changed? Or should we obey them blindly?
