This is a clear cut case of police in Baltimore suspecting someone of a crime and then arresting that person when no crime was committed. It's also a case of Baltimore police violated department policy.
In the Baltimore area (city and surrounding counties) there have been 99 deaths in police custody over the last 5 years. Roughly 20 a year. While at the same time the City of Baltimore has paid out $5.7m in cases which have contained police brutality during that same period. In those cases not one police officer was ever arrested or charged for their actions.
Her job is not bring money to the city but to protect law abiding citizens. Police can be criminals too. This is a case where those accused are police. That's it.
There is also a long history of deaths in custody of BCPD.
Baltimore's issue has always been since MLK riots of 1968.. was lack of jobs and business fleeing the city. Then to combat that issue.. Baltimore started getting "tough on crime" Giuliani style. Then began relying more and more on DoJ and other Federal funding so they sought higher arrest numbers. So thousands and thousands were arrested for some stupid ****.. In fact 600,000 arrest were made in a city of 620,000 during 1 year under Martin O'Malley. Being arrested, just arrested mind you, will harm your ability to get a job because it's considered part of your criminal record. So if you are arrested for "trespassing" or "jay walking".. it could easily cost you a job in Maryland. It wasn't until 2007 Maryland addressed BCPD and the City of Baltimore's policy of arresting just to arrest. But the damage was done. You have a large part of population who couldn't and still can't get a job because of it. That has a snowball effect.
