(RIO DE JANEIRO) — A violent police strike in northeastern Brazil has shed light on dissatisfaction among cops elsewhere in the country, with some forces threatening to protest as rowdy Carnival celebrations start. The strike by military police demanding higher salaries in the state of Ceara, and which led to a senator being shot, is a headache for President Jair Bolsonaro, a staunch supporter of police forces who has pledged to curb violent crime. “Of course, police strikes could spread,” said lawmaker Guilherme da Cunha of the state of Minas Gerais, where police obtained a 42 percent salary increase this year after threatening to strike.
