The Palestinian Arab press has been increasing in its reporting of corruption and strong-arm tactics by Hamas in Gaza lately, seemingly to increase its revenue (beyond the $150 million a month that the PA provides to Gaza.)
Today, Palestine Press Agency reports that Hamas is involved in drug trafficking and car thefts in Gaza. In addition, they report that Hamas is levying arbitrary fees on auto-repair shops in ways that look more like protection racket payoffs than taxes. Its court systems are adding large fees for judgments. In addition, Firas Press reports that Hamas is adding "tolls" on roads, pretty much stopping people and asking for money, a different amount each time.
The impression is that Hamas is building a police state with its terrorists doing whatever is necessary to extort money from the citizens it pretends to care about.
