If I'm pulled over when carrying a piñata, on what grounds can the officer legally break it open?

1

Is it within my rights to insist that he wear a blindfold?

I tee-hee’d on longPath’s reply…

But more specifically, probable cause comes into play here. Same as searching your ass. Location is likely to have an influence - “oh… you’re bringing in a pinata from Mexico, huh? Darn, I wish I was allowed to search pinatas…” :smiley:
