What kind of opinions you looking for? Legally its ok as long as you don't bring your guns with you, even the clear ones. Would be cool if you got light reflective tape on you or carry around a glow stick since most gear is meant to blend.
"Hey I'm the first one to say its a great country but its a straaaaange culture. This is a place where gun store owners are given a list of stolen credit cards but not a list of CRIMINALS and MANIACS. And now they're thinking of banning toy guns...AND THEY'RE GONNA KEEP THE F**KING REAL ONES!"
