That failed to answer a few questions. Is that garage attached or detached? If attached, then yes, it's home invasion. If detached, then it's strictly a property crime, and the family wasn't in any immediate danger, and he shouldn't have confronted the perp, (legally speaking). Shooting at the others that were running away was a stupid NO-NO, and he's likely going to get punished for that. He MIGHT be able to get the charges reduced for the initial shooting.
Now, the above being said, I side with the shooter, in that they were committing a crime, and deserved what they got. However, legal charges aren't decided by us......they're decided by arresting officers and local prosecutors.
