Brenda says there's a new law making carjacking a Federal offense. This is true but inapplicable. The relevant law is codified as Title 18 US Code section 2119. However, this law only applies to cars transported either across state lines or international borders, which did not occur in this case: "a motor vehicle that has been transported, shipped, or received in interstate or foreign commerce". The carjacking must have occurred during the transportation process; for example, if a Mercedes was imported from Germany and received in the US, then later carjacked, this law would not apply.
Brenda asks what a judge was doing in the park at 10:30 at night, but the judge was dead for two to three hours so he would have been in the park around 7:30 to 8:30 which is not late at all.
