In Denver, local activists are criticizing the city’s plan to use an abandoned warehouse that has no air conditioning to hold jailed protesters during next week’s Democratic National Convention. Last week, it was revealed the city had set up dozens of metal cages topped with razor wire inside a city-owned warehouse. A sign posted in the makeshift jail reads, “Warning! Electric stun devices used in this facility.” On Friday, demonstrators gathered outside the building to condemn the city’s plans. The weekly newspaper Westword has revealed the city once used the warehouse to store voting machines, but the facility had to be abandoned because temperatures became too hot inside.
