They burned down the CVS because they are stupid, short-sighted subhuman thugs.
Lots a failed supposition here. I highly doubt that filling badly needed prescriptions was a common occurrence for the healthy and strapping youths who were pillaging the aisles of CVS.
Well, I seen the fires burnin’
And the local people turnin’
On the merchants and the shops
Who used to sell their brooms and mops
And every other household item
Watched the mob just turn and bite ‘em
And they say it served ‘em right
Because a few of them are white,
And it’s the same across the nation
Black & white discrimination
They’re yellin’ “You can’t understand me!”
And all the other crap they hand me
In the papers and TV
‘N all that mass stupidity
That seems to grow more every day
Each time you hear some nitwit say
He wants to go and do you in
Because the color of your skin
Just don’t appeal to him
(No matter if it’s black or white)

It didn't hurt any that CVS had some bad-ass drugs behind the pharmacy counter and in the drug safe.
It doesn't appear that there was any of the "good stuff" left to catch fire.
Same thing happened in NYC during the sixties riots-drug stores, liquor stores and furniture stores just happened to catch fire-after they were looted.
