I can't stand Cruz, but he's been unapologetic about personal freedom no matter who it involves. I'm not so sure imprisoning a business owner was the right call here. Fine the business and move on to the next case.
Fwiw, I saw video of Cruz getting the haircut and everyone including Cruz was wearing a mask, so this in a roundabout way is showing businesses that they will still need to be smart about reopening and require masks and/or reasonable distancing and disinfecting SOPs. Hopefully this encourages people to continue taking this seriously as things slowly open back up.
I don't know how effective it will be, but other countries requiring widespread mask usage have done ok.
