Are we talking about the 1970's ?
Getting your knickers in a twist cos you are getting filmed ?
Every shop, mall, restaurant, fast food, goverment building, etc..... has " security cameras", even in the dr. Hell even campo colmados have them.
Every man and his dog has a dashcam or 2 in their vehicule...... how dare they film other people w/o their consent ?
Every dominican has a cellphone and will film anything of intrest.
One may not like to be filmed, as I dont, but the fact is you have been caught on camera dozens and dozens of times every single day in " first world " countries for the past decade. And its now here in the dr as well.
The only diffrence I see between the youtuber and the rest of the population, is that he is doing out in the open ( as holding camera ).
But dont be blind to the fact that if you pick your nose in public, it will be filmed, and it will probably be put on internet. If you are lucky the video will get 46 views, if you are unlucky it will get 46 million views.
So did the YTer deserve to get slapped around ? Of course not.
Should/could he have been more discreet ? Should: no, could: yes
