Justifiable Reraise?

[Piper Tim]

Been at the table for a couple rotations. Most of the table is weak-tight. UTG+1 plays a high percentage of hands fairly aggressively. Preflop I'd seen him raise everything from low suited cards, to mid and high pocket pairs. UTG+2 calls a lot, but rarely raises. Is the reraise justifiable or a good way to spew chips?
