My point was aimed at the Brazilian police force as a whole not specifically SP Pol but since you mentioned it...
They've been 442 fatal police shootings in SP since 2002.
That works out a one police killing every 2.5 days! These statistics cover less than 11% of the national population of 185 million. SP isn't even the worst place in Brasil for such killings either.
I'd hardly say it's uncommon would you? Pretty recent as well wouldn't you say?
Where are your facts? Keep pitching them down and I'll keep knocking them to the boundary.
