In The Italian Job, there's a scene where the crew is discussing the plan on a rooftop balcony in LA.
CHARLIE: I want audio surveillance on his phone.
LYLE: Oh, yeah, I been wanting to try something. I crack into the phone company's remote monitoring system, and fool it into thinking there's a legal tap on the line. Just reroute the digital copies of the calls to our own listening post. I been doing it to my ex for years.
I don't understand the two statements in bold.
If Lyle has already been doing this to his ex for years, why would he say he's been "wanting to try it"? Hasn't he already tried (and succeeded) at it?
