From [Gallup] [Among white people] overall confidence in the police has risen slightly in the past two years, with 57% of Americans now saying they have "a great deal" or "quite a lot" of confidence in law enforcement -- matching the overall average for the 25-year Gallup trend. Specifically the poll reveals that only 30% of Black's have confidence in police and 45% of Latinos have such confidence. The number for Latinos has dropped from 59% in 2014 to 45%. Overall 58% of white people have confidence in their police. Among liberal whites only 39% have confidence while 67% of conservative whites have confidence in police.  

The overall percentage of Americans who said they were confident in the police changed little from 2012-2014 (55%) to 2015-2017 (54%). But major differences have emerged among various subgroups over the past three years.

The 2015-2017 polling shows a widespread loss of confidence among groups that generally are in line politically with blacks -- Democrats and independents who lean Democratic, Hispanics, liberals and those younger than age 35. Confidence among Republicans and Republican leaners, whites, conservatives and those aged 55 or older has been stable or has increased slightly. As a result, gaps between groups are now evident by age, ethnicity and ideology, along with a larger gap by party affiliation.

The difference is especially pronounced between liberals (39% confident in 2015-2017) and conservatives (67% confident). And in the June 2017 poll, the percentage of liberals who are confident is down to 38%, the lowest since at least 2000, while conservatives are at 73%, their highest mark going back to 2000.
