Sure! The comment I replied to, seems to imply that hijacking UPS trucks is a non-existent, or rare event. A simple Google Search seems to indicate that it happens all the time. There for making the original OPs concern somewhat valid.
Your logic is off. If you spend a lot of time around goats then worrying about a goat attack is valid. Similar to how people in North Dakota do not worry about hurricane but people in the Florida Keys do.
