Why can we unite behind Cecil the lion but not Sandra Bland?

For many Americans, the past three weeks have felt like the final straw in a year that has seen unprecedented recognition of police brutality against people of colour. Each day since the death of Sandra Bland on July 10th has heralded a new theory or an additional piece of evidence; this morning was no different, with the release by Texas police of new CCTV footage in an attempt to quash the wilder conspiracy theories about her death. Questions – very important questions – still remain, however. The inconsistencies in the case seem myriad; the trajectory from failing to signal while changing lanes to suicide in a cell block seems odd.
