That's no excuse. Niceness does not make up for jack-booted thuggery. You apparently explained to the TSOs exactly why chilled airside-purchased water was unacceptable, yet the two of them still insisted on confiscating your baby's water. Even though liquids for babies are explicitly allowed. They may have been polite, but they were power-tripping and bullying you. Don't fall for it.

This type of behavior is exactly why no TSO deserves any respect from any passenger until this disgusting disgrace of an agency develops some accountability for it's power-tripping agents. These two agents should be fired with prejudice.

I know it's hard, but the appropriate response for agents doing this specific behavior is to loudly say, "HOW WOULD YOU AND YOUR WIFE FEEL IF THIS WERE DONE TO YOU? DON'T YOU FEEL ASHAMED TAKING FOOD AWAY FROM A BABY AND HER MOTHER? YOU DON'T DESERVE THE PRIVILEGES OF AMERICAN CITIZENSHIP. F YOU AND GO TO H." You want the crowd to hear you. You want to make them so ashamed that they shrink into themselves and wish they had never been born. That's the only way to stop this abuse.

TSA started this. TSA reaps what it sows. I hope the founders and leaders of this agency rot in filth while being spat on by true Americans.
