You really think the government would do anything more than slap this guy on the wrists and maybe make him serve a couple of years before releasing him right back out into the general population so he can try - and possibly succeed - in killing another baby?
Wow, you really are an optimist. Not to mention delusional. I don't know what it's like where you're from, but around here? The government is just as corrupt as the criminals, if not more.
And for the record, killing him would solve the pesky issue we have of babies being dropped from windows.
