Will Apollo mistakes be made with Mars?

MattSparkes writes: "In some ways the Apollo 11 mission was a great success; the astronauts got back to Earth safely after walking on the moon. However, it was a massive disaster in terms of quarantine procedures — the astronauts had to leave the landing capsule to enter the quarantine module, after it was found that the crane on board the ship wasn't strong enough to raise it. Would NASA be able to protect the Earth from Martian pathogens if it successfully returns soil samples from the Red Planet?"
