For the gazillianth time, he’s seeking the crippling of computer security and privacy system with a back door for law enforcement:

Attorney General Eric Holder, the US top law enforcement official, said it is “worrisome” that tech companies are providing default encryption on consumer electronics. Locking the authorities out of being able to physically access the contents of devices puts children at risk, he said.

“It is fully possible to permit law enforcement to do its job while still adequately protecting personal privacy,” Holder said during a Tuesday speech before the Global Alliance Against Child Sexual Abuse Online conference. “When a child is in danger, law enforcement needs to be able to take every legally available step to quickly find and protect the child and to stop those that abuse children. It is worrisome to see companies thwarting our ability to do so.”

Holder’s remarks, while he did not mention any particular company by name, come two weeks after Apple announced its new iPhone 6 models would be equipped with data encryption that prevents authorities from accessing the contents of the phone. At the same time, Google said its upcoming Android operating system will also have default encryption.

The encryption decision by two of the world’s biggest names in tech is a bid to gain the trust of customers in the wake of the Edward Snowden surveillance revelations.

Holder said he wants a backdoor to defeat encryption. He urged the tech sector “to work with us to ensure that law enforcement retains the ability, with court-authorization, to lawfully obtain information in the course of an investigation, such as catching kidnappers and sexual predators.”

Mr. Holder, I need to explain something to you, and I will talk slowly.

A backdoor is a security hole, and once you create a security hole, it can be used by anyone.

You are asking every American citizen to make their systems less secure for your convenience.

This is a very bad idea.
