Not all states give citizens as much leeway in protecting their
personal property. States like California allow citizens to protect
their homes with deadly force if they feel that they or another person
are in physical danger, but does not extend to theft, and it only
protects residents in their home, and not in cars or at work.
In New York you cannot use deadly force if you know with certainty
that you can avoid an intruder by retreating. You can use deadly force
if you are not the initial aggressor in an altercation within your
home.
Other states with limited, little, or no castle law or case law giving
citizens the rights to protect their homes using force include: Idaho,
Pennsylvania, South Dakota, Iowa, New Hampshire, New Mexico, Virginia,
Vermont, and Washington, D.C.

There is also the issue of how the burden of proof is handled.
You might eventually prevail in a lot of states but it could cost you
a six figure lawyer bill because it is up to the homeowner to prove
they were justified.
Florida has a bill in the legislature that puts the burden of proof on
the state before they can even bring the case.
