Batman might have low interpersonal communication skills, but he is, rather famously, a great detective.
The first thing he does is gather the reports from the rest of the Justice League. If this problem is big enough for Arrow to call heavy hitter League members to look at it, and somehow small enough for Batman to leave it for after the Arkham breakout, than there is time enough for Batman to gather outside information before listening to Arrow.
What he finds is... strange.
He reads Wonder Woman's report first. Not out of any disrespect for Captain Marvel, of course, but that man was not consistent with modern spelling.
She reports that she spoke to the owner about his home security product, asked if it was safe under the lasso of truth, and left after positive confirmation. It was less than a standard sized page long.
Safety... Batman mulls this over. The lasso compels the truth. Lying by ommission was difficult. A random civillian would likely not have the capability.
So the product does not cause harm under the view of Fenton Securities, and has been empirically proven to be effective by the entire city and Flash himself.
Batman considers. Fenton, talk to Arrow, or Marvel's report?
He decides to look into Fenton Securities.
The CEO was one Daniel James Fenton, born and raised in Amity Park, Illinois, USA. Older sister, who was in Gotham, intending to be a psychiatrist in Arkham (Batman flags this for later on principle). No social media for them, or the parents. The parents were inventors, for... His brows rose. That was a government code used in projects by Amanda Waller. He flags that too.
Danny's friend Samantha Manson had an instagram, where she made many posts about environmentalism. Danny's name occasionally appeared in sentences, untagged. He appeared in photo backgrounds. Black hair, blue eyes, no suspicious scarring or photoshop detected in metadata.
He did not go to college. He started the business three years after high school, with no investors.
Fenton Securities is a sole proprietorship.
A city wide company has one person at the head of it, fronting the start up capital from... somewhere, he'd set Red Robin on that (he was better at financial records than Oracle). There was seemingly no one else sharing in the management or profits.
They use a local third party delivery service, which was slightly non-standard but not suspicious. It became suspicious when Batman saw that labor margins for Fenton Securities itself were 0%.
There are either no employees, or they aren't getting paid.
The goods are manufactured, inspected, and shipped from a single warehouse.
Batman would have to double check that the man Wonder Woman met was actually this Danny character. This stretched the bounds of belief for what a single human could do alone, legally, and 'safely'.
For the moment, Batman set this aside and turns to Captain's report. If a deep dive in Fenton was not proven necessary, it could wait.
This report is three pages long. This is nothing to comment on. Captain either rambles or writes two sentences and considers something complete.
The first was a typically rambling assessment of, Batman blinks in surprise, Arrow. Captain noted that he seemed "obsessive" over the issue when talking to him before and after the investigation. Insisting that there had to be something Diana missed. Diana.
Marvel went on to explain that he went in disguise to the warehouse, which was clean and had no people in it. Rather, there was, supposedly, a god, who was handling quality control. And manufacturing. Through magic, and a 'nat portal probably dont worry tho seems under control by the god'.
The report does not elaborate.
The last page has a single paragraph concurring with Wonder Woman, and recommending, 'constantean if it becomes a problem otherwise let sleeping dogs lye :) .'
He does not want to work with 'constantean'.
He does not want to get involved with magic bullshit, that is set to helping people for once. By getting into the house of every person in the city.
Talk to Green Arrow in person, or try and meet this Fenton character, who might be a front for a god?
Decisions... decisions...
