If a baby were left on your doorstep in the middle of the night, would you raise him/her as your own?

Actually it did happen exactly like this in my hometown 5 years ago. I was a licensed in home day care provider, when one morning I went out side to retrieve my husbands news paper and low in behold there was a newborn baby left on my doorstep. I thought for a second I want this baby it was a brand new baby boy. Someone thought about me in mind to have placed this beautiful bundle of joy on my porch. Than reality set in and I had to involve the authorities and then the child protective agency was involved and the news media and it was a blissful moment turned nighmare.....Eventually they did locate the person who gave birth to the baby and if i'm not mistaken they were reunited after intense therapy, parenting cles etc. I have always questioned if I was given the chance again would I have done it differently, and I can't say I would, because somewhere would be parents missing their child and I would hate to lose him/her after having bonded with the child. In the few moments I spent with this beautiful baby I loved him....
