Venezuela's opposition says that thugs are
robbing
protesters.
I believe the accusations, but they probably have nothing directly to
do with President Maduro. Thugs in Venezuela have been crooked since
long before Chavez. He was unable to make them stop, but neither
could anyone else.
While Chavez was president, the head of a state agency I worked with
told me he had been (in effect) held for ransom by thugs, who stopped
him as he was driving and made up charges against him on the spot.
The fact that he was the head of a state agency didn't help him to
escape.
