The Associated Press reports: When Sandra Tamari arrived at Israel’s international airport, she received an unusual request: A security agent pushed a computer screen in front of her, connected to Gmail and told her to “log in.”

The agent, suspecting Tamari was involved in pro-Palestinian activism, wanted to inspect her private email account for incriminating evidence. The 42-year-old American of Palestinian descent refused and was swiftly expelled from the country.

Tamari’s experience is not unique. In a cyber-age twist on Israel’s vaunted history of airport security, the country has begun to force incoming travelers deemed suspicious to open personal email accounts for inspection, visitors say.

Targeting mainly Muslims or Arabs, the practice appears to be aimed at rooting out visitors who have histories of pro-Palestinian activism, and in recent weeks, has led to the expulsion of at least three American women.

It remains unclear how widespread the practice is.

However, asked about Tamari’s claims, the Shin Bet security agency confirmed she had been interrogated and said its agents acted in accordance with the law.

Israel has a long history of using ethnic profiling, calling it a necessary evil resulting from its bitter experience with terrorist attacks. Arab travelers and anyone else seen as a risk are often subjected to intense questioning and invasive inspections, including strip searches.
