The family is left to believe that the individuals seem smarter than the detective and his training, and knowledge or that there are some kind of cover-ups and corruption—which may explain the statements made in the body-worn cameras, as being familiar with the residence, and many of the individual(s), the individuals past and continuous arrest and release records and the officials’ lack of gathering any evidence to prove or disprove information by their assertion or refusal to review further evidence to close this case.
As discussed with others, possibly… a lack of ability, a cover-up, or a Crime clearance rate…
Either way, with any of these scenarios, doing nothing impedes any justice and is a public safety concern for others on many levels. Especially when laws allow an officer to perform, each incident(s), that a common citizen cannot conduct when offenses are committed.
You’re left to worry about who will show up in an emergency and if they will do their diligence and properly investigate…or disregard policy and procedures leaving others unsuspecting and vulnerable.
