I would like to propose that whenever these marchers shout "Si! Se Pueda!" [Yes! we can!], we reply "No! Usted no pueda" [No! You cannot!].

BTW. I finished your book. Outstanding!

Even better, use slogans with "criminal" in them. It's the same word in both languages, and they hate it like the devil hates holy water to be reminded that they are criminals.

My suggestion:

"Illegal aliens are criminal invaders!"

"!Extranjeros ilegales son invasores criminales!"

See, it's understandable in both languages, it even rhymes and works as a nice chant in spanish, and they HATE it.
