Home Alone is a family film, so director Chris Columbus and writer John Hughes wisely chose to keep the film free of any blood and gore, even though some of those traps look like they really put a hurting on the robbers.
Fans have speculated about what the robbers would actually look like if they'd been hit in the face with a steel pipe or beaned with a brick, so animator BitMassive added the gore effects and created Home Alone With Blood.
So far BitMassive has added bloody effects to four scenes from Home Alone 1 and 2, but he could run with this premise forever if you consider how many movies contain slapstick violence in need of a gory makeover.

I remember when the first Home Alone movie came out and Kevin had rigged up all sorts of boobie traps and thinking that these traps could easily kill someone. I didn't find it funny at all. Took the shine off the movie for me. The part with all of the broken Christmas ornaments on the floor and the villains stepping on them in bare feet... wth? Apparently I gave a problem suspending belief with movies like this one.
