"WPRU" had the rights to People's Court, but Storefront/LKK/whatever "WPRU"'s owners call themselves now, will probably just move it to "WSJX" (Fox) or WSJP-LD (CW).
And I put the calls in quotations, 'cause both WPRU-LP and WSJX-LP have been silent for over a year and a half. They're both just branded subchannels of WSJP-LD now, if WPRU's even exists anymore.
As for the language thing, it's frequently said here that only about 1/4 of Puerto Ricans are actually bilingual.
I'd say a good portion after that 1/4 can read, write, and understand English pretty well. Speaking it, however, is another thing entirely. That's thanks to the public education system which for decades, when it comes to English, has had a strong emphasis on reading, vocabulary, and grammar, but very little on oral communication. Basically, most bilinguals here are either mainlanders (be they of Puerto Rican decent or not), have spent time on the mainland, or just studied in private schools.
