Welcome to our Friday roll up, where we highlight the most absurd and concerning stories we are following this week. Dad sued for slander because he criticized the education system

Careful what you say about your kid’s public school curriculum.

The company behind a controversial common core math program in North Carolina is suing a dad for libel and slander.

The parent of a high school student has been on a “crusade,” the lawsuit claims, against the math program. Instead of teacher led instruction, students are taught through self-discovery.

He and many others see strong evidence that the old methods are better. That’s why he created a Facebook group and website where he lays out his criticism of the program.

We checked out the guy’s website, and it is full of well thought out rational criticism. Whether he is correct or not is irrelevant. He is just expressing an opinion on the type of education his child will receive in public school.

We’ve moved beyond gender neutral pronouns and triggering micro-aggressions. Now just expressing any old opinion offends people.

Apparently you can’t do that in the USA, anymore. If you offend someone with constructive criticism, they turn around and sue you.

The Pentagon is currently testing high altitude surveillance balloons in several midwestern states.

Flying at about 65,000 feet, the balloons are able to track multiple vehicles at once, in any type of weather, using radar.

The Pentagon says the purpose of the solar powered unmanned balloons is to “provide a persistent surveillance system to locate and deter narcotic trafficking and homeland security threats.”

The data gathered over broad swaths of the country will be saved so it can be rewound and reviewed after the fact.

Big Brother is really watching.
