It's extremely hard to convict officers accused of serious crimes.<br />Since 2005, 70 officers in this country have faced charges related to an on-duty shooting.<br />Only 23 were found guilty.<br />The outrage pointed at the acquittal of Baltimore police officer Edward Nero in the death of Freddie Gray further emphasizes this point.<br />It's also something seen in other cases around the nation, like in Cleveland after a grand jury didn't indict the officer who shot 12-year-old Tamir Rice.<br />Researchers at Bowling Green University said about 1,100 people are killed in police shootings every year.<br />But in 2015, just 18 officers were charged and only three were convicted.
