Those are the same numbers portrayed on every website & news service, but as your excerpt noted they're all directly from the mouth of the City government which has every reason in the world to embellish them. First off the fires, I can find only 4 considerable fires, a CVS, an under construction senior center, a liquor store and an abandoned warehouse (right next to the senior center). Cars? I can only find images/footage of about a dozen cars with heavy damage, though there are definitely a lot more cars with minor damage (slashed tires, broken windows, etc). Most of the damage to those cars is being caused by a very few people, one youtube video shows a single individual smashing 3 car windows in under 5 seconds. Officer "injuries" are a bit harder to track, but of the "98 injured" is being thrown around, of those at most 41 required "some form" of medical attention and only 13 apparently had injuries significant enough to take time off of work. And as far as the arrests, the BPD has released over half of those arrested, While I admit my numbers may be a bit low for Baltimore specifically, but the numbers/impressions out of the press & city government seem to be extremely high.
