Greek authorities are warning journalists not to cross the line -- into Olympic venues, that is.

Public order minister Giorgos Voulgarakis said guards will take action against anyone -- carrying a press card or not -- who is caught on Olympic sites without permission.

"If an officer with orders to protect a site sees something illegal and gives repeated warnings, he could act in a way that could have very serious consequences," he said.

The stern words came after British and German journalists were detained for illegally entering Olympic sports complexes at night in apparent attempts to test security measures.

"It is a strange behavior because they could have gotten permission to visit all venues," Voulgarakis told Flash radio. "I would tell journalists to treat Olympic security very seriously and not see it just as an opportunity for a story."

Temporary Amnesty for Draft Dodgers

Greek men who left the country to avoid mandatory military service will get a free pass back during the Olympic summer.

From Aug. 1 to Sept. 30, border authorities will not check on conscription status for returning Greeks. The waiver for draft dodgers, however, will end when the Olympic road show moves on. The Olympics are Aug. 13-29 and the Paralympics are Sept. 17-28.

Bank Issues Special Coin for Olympics

The Bank of Greece issued a new 2-euro coin to commemorate the return of the Olympics to their ancient birthplace.

The side of the coin that currently displays the ancient Greek goddess Europa, which gave the continent its name, will be replaced by another image: the discus thrower.

Considered by many to represent the perfect athletic form, the famous statue of the discus thrower was created about 460 B.C.

"We're honoring a unique event, the return of the Olympics home to their place of birth -- Greece," Bank of Greece governor Nicholas Garganas said.

The bank said 50 million commemorative 2 euro coins will circulate throughout Europe.

Nothing Wrong With Demonstrating

Greeks will retain the right to demonstrate during the Olympic Games, despite all the security measures being put in place, the government says.

"The government will not accept infringements of citizens' rights, because if this were accepted then there is the danger that the infringements will get worse," said government spokesman Theodoros Roussopoulos.

Demonstrations are commonplace in Athens, staged by labor unions, students and even a group opposed to the Olympics.

Amnesty International and Greece's independent Data Protection Authority urge the government to dismantle the main network of surveillance cameras after the games.
