This is an interesting issue.
A friend of mine had a similar incident about 7 years ago.
Kid(17) broke into his house on a long weekend as he was normally away weekends with his family.
This time, he just happened to be sleeping working overtime shifts, the kid came in through the window of the basement, made noise as he was trying to get in.
My buddy found him in the basement disconnecting some very high end audio equipment, struggle started, kid lost.
The kid was tied up and the police were called.
No conviction on the kid, my friend is charged with forced confinement and assault and ended up doing time as he had a previous bar fight assault conviction when he was 18.
Doesn't make a lot of sense to me.
