Are LLC's as iron clad in protecting you as people suggest?

[Mareno Rathell]

I hear you should put your properties under an LLC to protect yourself, your savings & your home from anything that may arise from a lawsuit associated with one of your properties, but I wonder if that is just something people stated repeating to others without knowing if it's factual. I've heard a good lawyer could find holes in that setup and wipe you clean.
