Can I get in trouble for dressing up as a terrorist for Halloween? ?

Go right ahead. One less village idiot.

No, you won't get into trouble, although, you might get shot.

Not funny.  Expect trouble.  

If you put on a fake bomb vest you can expect to be shot dead by police. Ill be watching the news waiting.

Sure....and make sure you trick or treat at an airport

If you wanna really be an authentic terrorist...
Dress up like POTUS.
He's killed more US citizens than anyone in your lifetime.

Obama, what we gunna do?
Inject him with the TrumPence Flu...inject him with the TrumPence flu...
Or should we chop him up like the Saudis do? 🤣

KNOCK KNOCK    image of a terrorist  ?

  definition of TERRORIST  a PERSON who uses UNLAWFUL VIOLENCE and INTIMIDATION , especially against  CIVILIANS , in the pursuit of POLITICAL AIMS.....

.. that describes an event  that took place during a POTUS stroll  for a PHOTO OP might want to purchase a  TRUMP Halloween mask for  authenticity

its NOT illegal to wear a Trump Halloween mask

suggestion practice   how  to   avoid  propelled objects such as   eggs and tomatoes and refuge  in certain  neighborhoods  in other  areas may be  welcomed and embraced  intentionally infected with covid 19

  yet Trump tries to humiliate and INTIMIDATE  people who wear surgical  and protective HEALTH mask

Yes, so stick with something else, just not that. How about a pirate or a movie character like "Marty Mcfly" or "Rick and Morty".

That's stupid. It isn't even funny to dress up as a terrorist. 

Uhhhhhh sure.  

Depends on whether your costume is realistic or comical.

Nope just dress up as a jehoavah witness

To someone with common sense and civility, they won't care.  To the person with radical leftist values, they will be outraged.  But really, can't you think of anything else to dress up as?  And in reality, a terrorist is not funny like you think it is.
