It seems like the lack of context gets used to skew peoples perception of an issue just as often as false information, for example classifying gang violence and robberies as "mass shootings" without giving any other details. This can be applied to just about any topic out there. It's easier to leave out details and use esoteric language, than it is to lie about what happened. People can at-least deduce bias/flaws given enough narrative, and a track record of inaccurate context damages an organization's reputation.
Most shootings that look like ‘gang in gang’ are probably ‘gang on gang’ violence. But, that doesn’t mean a specific shooting was actually ‘gang on gang’ violence. Gang members also shoot people for personal reasons unrelated to being a gang member. And they also get shot for reasons unrelated to being a gang member. If the assumption is it’s always ‘gang in gang’ and it’s always reported as such then that’s a lot of biased and often incorrect information being reported as fact.
It’s not uncommon for gang members to just go out and randomly shoot stuff the same way young rednecks shoot at road signs. The difference is gang members in cites are vastly more likely to randomly hit someone due to population density.
Personally I would prefer reporters to stick with known accurate information rather than what whoever they spoke with believed to be accurate context. Shootouts between drug dealers could be over territory, or just about anything else. Unless they spoke with the people actually involved it’s all supposition.
