The breaches have been made using a popular cordless household tool known as a reciprocating saw that retails at hardware stores for as little as $100. When fitted with specialized blades, the saws can slice through one of the barrier’s steel-and-concrete bollards in a matter of minutes, according to the agents, who spoke on the condition of anonymity because they were not authorized to speak publicly about the barrier-defeating techniques.
Now, I'm calling solid digestive waste from a male bovine.
I own such a reciprocating saw (AKA,
“Sawzall”*), and am very familiar with its capabilities. Though I haven't been directly involved in cutting concrete, I've been around enough of it to know what it involves.
Even with the specialized blades, there's no way that a Sawzall will cut through those concrete-filled bollards in what can honestly be described as mere
“minutes”. It would take a very long time to cut through those with a Sawzall, and you'd go through several batteries before you completed even one cut.
Concrete cutting is usually done with equipment that is much bigger and more powerful than a Sawzall, and highly specialized for that purpose.

* Though, as I said before, while the term
“Sawzall” properly applies only to those reciprocating saws made by Milwaukee Tool, which owns a trademark on that name, it is common in the construction trades to use that name to refer to reciprocating saws of any brand, including my DeWalt.
