How safe is Paris currently for a tourist?

Generally - safe.

Just like any big European city (ie as long as you're not wandering alone at 3am, or leaving your bag open in prime pickpocket areas, you're unlikely to have many issues)

Paris is safe for a tourist. 

Not so...google Roma gypsy robbery Paris, migrant rape Paris, cash robbery Paris

Quite safe. Just watch out for petty criminals and pickpockets.

Just as safe as any other big city in a first world country. The biggest threat facing tourists to Paris as of spring 2019 was pickpocketing. While Paris has admittedly taken a significant knockdown in world city safety ratings due to recent terrorist attacks, violent crime is still generally uncommon in the capital. OSAC, the US Bureau of Diplomatic Security, notes that tourists are generally safe in the city, and that street crime such as pickpocketing remains the primary concern.

No bombs, I think
