Do leos tend to Lie alot?

I knew one Leo liar, at least I think he was a Leo. But he was also pretty immature, much like the lower type who are also "skirt chasers" or man whores, whatever you wanna call it, lol, and big whiners.
But most of the Leos I know are pretty up-front honest and loyal, and good-natured people. There's good and bad in every sign.
