drawing from my own experience in an american city where crime has been mostly on the decline, this is absolutely plausible:

Last March, a representative of the public prosecutor’s office said there was no rise in criminality, but that the gradual widening of internet access for Cubans increases “the visibility” of the kind of crime that previously stayed in the shadows, and that online platforms are “spaces that also distort things that have happened.”

There may be an increase in petty crime, idk, I know the economic situation is not great rn, but to say that crime is getting out of control based on increasing social media reports (in a country which until recently had low levels of internet access), is not a reliable measure, and the "independent journalists" could be about as reliable as the self styled journalist that runs my local facebook crime watch page and just sits on the police scanner and sensationalizes every little thing that comes across it. Or they could be reputable but I'm not super inclined to give capitalist media criticizing a socialist country the benefit of the doubt
