Like the people who live in the village, in general most of them do not know about politics with good, so that they are very much in deceit by the state officials

Yes, that is very common, when people aren't informed enough, or with enough knowledge to see through the lies of the politicians, it is just a matter of time for them to get deceived.

And the public can not protest for all this because there is no evidence

There is always evidence, in the case of Venezuela there are tons of evidence about the extreme corruption and that's why these people are having a lot of problems with the international community. The only reason they aren't in jail is because they have the country kidnapped and control the army, but this should eventually end as other countries like Colombia get overwhelmed by the amount of Venezuelas looking for help across the borders.
