It is wrong..
1. Double Jeopardy only applies to the same crime. Think
Michael Slager, the cop that killed Walter Scott. Slager was charged with murder (state) after a video surfaced which showed him shooting Scott from behind while Scott was fleeing, and which contradicted his police report.
In June 2015, a South Carolina
grand jury indicted Slager on a charge of murder. He was released on bond in January 2016. In late 2016, a five-week trial ended in a
mistrial due to a
hung jury. In May 2016, Slager was indicted on federal charges including violation of Scott's civil rights and obstruction of justice. In a May 2017
plea agreement, Slager pleaded guilty to federal charges of civil rights violations, and he was returned to jail pending sentencing.
[4][5] In return for his guilty plea, the state's murder charges were dropped.
1 act, multiple charges.
