World at War: Trying to head off a predicted terror attack, Belgian police arrested 21 people in 27 raids in the past day, but didn’t grab the man they wanted most, Salah Abdeslam, who is believed to be the planner of the Paris terror attacks. Among other locations, the police also sealed off at least two sections of central Brussels, but no weapons or explosives were found.

Despite putting Brussels on high alert for an attack, authorities offered no more specific information than that places where large numbers of people congregate could be targeted.

Brussels is now in its third day of lockdown. Schools and subways are closed while security personnel flood the country.

Small Screen: Ignoring legal threats from lawyers for Tampa Bay quarterback Jameis Winston, CNN last night aired an independent documentary about rape on college campuses.

The Campaign Trail: What’s a day without Donald? The billionaire presidential candidate said on ABC News yesterday that he would bring back the torture technique known as “waterboarding” to interrogate terrorists. “Waterboarding is peanuts compared to what they do to us,” Trump said, citing the beheading last year of American journalist James Foley in Syria. “What they’re doing to us, what they did to James Foley when they chopped off his head, that’s a whole different level and I would absolutely bring back interrogation and strong interrogation.”

OK, there’s more. Two days ago Trump said he saw a television report the day of the 9/11 attacks about thousands of Arabs in New Jersey cheering as the World Trade Center towers tumbled. “I watched in Jersey City, New Jersey, where thousands and thousands of people were cheering as that building was coming down. Thousands of people were cheering,” Trump said.

No one else has a record of such a thing happening.
