I think BPD does the best they can with what they're given. They're tremendously short staffed, have garbage equipment and garbage vehicles.

Officers in Baltimore respond to 20+ calls per shift, EACH. Many of which require reports. When you see two officers sitting next to each other, they may not even be conversing. They're likely writing (or at least starting) a report from the call they just left. Until the next call comes in, before they're done writing the report from the last one.

The vehicle situation also forces more than one officer per vehicle. For your situational awareness, most districts (of which there are 9) have four Sectors. Each sector has four posts. So each shift has at least 16 officers per district. If a sector only has 2 working patrol vehicles, that means two Posts have to ride together... Meaning only one call can be covered at a time for two posts.

It's hard for officers to proactively conduct traffic stops when they're busy working double or triple shootings. You can't expect miracles from overworked and under-supplied employees.

Edit: also worth noting, is they don't get paid shit. Baltimore is one of, if not THE, lowest paying jurisdictions in the area. Another reason why nobody wants to work there.
