Interesting topic but the statistics seem pretty lean.
I did see several links about Ohio robberies but not specifically crash and grab.
Here's a graph that shows an increase in armed robberies across five years but no reference to the number of THC outlets so what good is it? All I'm thinking is that big picture somewhat legit stats may not be available.
Sorry so small. Link below has a better display.
