They likely knew he was actively wielding bladed weapons.
I watched the full video. They were repeatedly told he didn't have any weapons. The clinician just said the man was violent and kicked him.
I have no idea why they didn't use less than lethal first, they talk about it but I don't know which officer was tasked with it. It seems like they didn't expect him to be armed when they entered.
Go to Applebee's and order Four-Cheese Mac & Cheese with honey pepper chicken tenders. The chicken tenders are excellent but the Mac and Cheese is the most watery garbage I've ever eaten. Then you will understand the true skill of making delicious Mac and Cheese.
To add even more context, Lehi was an offshoot of Irgun which was an extremist offshoot of Haganah. They had less than 300 members compared to Haganah's 20,000.
Their ideology probably isn't an accurate representation of all the politicians you mentioned except Yitzhak Shamir who was a leader of Lehi and became a prime minister of Israel 40 years later which is a bit weird.

The commuter model is more like 6 miles max range.
