That’s right. Barack Obama was president, and Janet Napolitano was Secretary of Homeland Security. And the Border Patrol responded to being attacked with rocks and bottles by deploying “pepper spray and other means” against illegal immigrants storming the border.Of course, that was nothing new for the Obama-era Border Patrol. According to a recent report in The Washington Times:‘The same tear-gas agent that the Trump administration is taking heat for deploying against a border mob this weekend is actually used fairly frequently — including more than once a month during the later years of President Barack Obama’s administration, according to Homeland Security data.’Further, “Border authorities also use another agent, pepper spray, frequently — including a decade-high record of 151 instances in 2013, also under Mr. Obama.”Shhh. Don’t tell that to California Democrat Sen. Dianne Feinstein, who responded to the recent use of tear gas by saying, “It’s horrifying to see tear gas used on mothers and young children as they seek refuge in the United States. That’s not what America should be.”Or Massachusetts Democrat Sen. Elizabeth Warren, who tweeted in response: “Mothers and their children walked hundreds of miles and fled unspeakable horrors in the hope they would find asylum here in America. Instead of being met with compassion, they were tear gassed. That is wrong. It’s immortal. We should be better than this.”Or Hawaii Democrat Sen. Brian Schatz, who tweeted Sunday, “Tear gas across the border against unarmed families is a new low.” (Actually, as pointed out above, it’s not a “new low” at all — it happened an awful lot when Barack Obama was president.)Less than an hour later, Schatz tweeted out a whopper: “Why tear gas? Is this consistent with the Conventions on Chemical Weapons?”Apparently, it took one of Schatz’s eagle-eyed staffers just a few moments to explain to the senator that use of tear gas for mob control purposes is sanctioned by international agreements on chemical weapons. He deleted the tweet forthwith.
