Technology behemoth Apple is taking a hard stand against the U.S. government in a case it says could set a dangerous precedent for government overreach after a federal court ruled Tuesday that the company must assist the Federal Bureau of Investigation (FBI) and break into an iPhone recovered from one of the suspected San Bernardino shooters.

In an open letter posted online, Apple president Tim Cook states that the company opposes the court order (pdf), which essentially demands that Apple build a “backdoor to the iPhone.” Such a move, Cook says, not only “threatens the security of our customers” but would have “implications far beyond the legal case at hand.”

Cook continues:

While Cook states outright that he has “no sympathy for terrorists,” he said that the “significance of what the company is demanding” threatens far greater damage to the American people.
