According to the US State Dept. the crime of insulting Chavez carries a maximum 1 year sentence. The law of course stipulates that the insult be "in a very public manner" so the reality is it is limited to media criticism and not individual criticisms. I'm sure the Wikipedia is great and all but relying on it for information like this is a really bad idea.
Here in the good old USA land of freedom we have "Food Disparagement" laws. Of course we use civil courts instead of criminal courts to go after people who violate these laws the effect is still the same.
The Venezuelan system, however imperfect, is meant to reduce outside influence on the electoral process while the US version is meant to protect food manufacturers from suffering a loss of profits that might result from someone criticizing the crap. Which seems the more reasonable to you?
Mexico also has desacato laws but I haven't heard much complaining about them lately.
