>Homeland Security Secretary Kristi Noem said the president ordered the color change to further discourage illegal crossings

Old man wakes up with a stupid idea and suddenly it's policy :(

The cruelty isn't just the means; it's the end.

As I've often said, BIG people lift others up. SMALL people try to cut others down to their level.

All cruelty springs from weakness. We are collectively experiencing the outcome of weak people obtaining power. The remaining work is to disempower them if you want to make empathy and compassion great again.

Do most border crossings happen during the day? Also - does black painted metal get significantly hotter than raw metal? Couldn’t the black paint act as an insulator and actually hold and release the heat itself?

Also does it heat to a higher level or just speed up the rate of heating?
