Actually, I heard that bars on windows of construction trailers is normal... so that thieves and scrappers don't steal valuable materials like copper from the trailer.

But either way, the optics are horrible for the O'Biden Administration. Most people will think it's a cage.

P.S.: Back around this time last year, I thought the Chinese Wuhan hospital was actually a prison because of the window bars... but I was wrong. Prefab trailers are just shipped like that
